21 million supply of bitcoin won't change forever. It's there to stay and can't be modified. As said explained well by ranochigo, there has been a lot of "upgrades" made by those fork coins and have replaced the supply limit into lower or higher one dependent from their stand towards the upgrade that they want.
But at the end, they're not bitcoin but only became forked coins or mere altcoins.

Actually everything in Bitcoin can be changed, as long as there is the consensus for it.
The miners that have accumulated a lot of Bitcoin, while the whales that only wish Bitcoin price to be increasing, are they the one that will agree for a change in the total supply of Bitcoin to surpass 21 million, I think that is just not going to happen. I believe this is the last thing that can happen to bitcoin, even to be the last thing seem more of an understatement because the chance for such to happen is not realistic. Not realistic because people do not want their Bitcoin to have lesser value, people want it to appreciate, while increasing the total supply will reduce its value in term of price, and this, miners and holders will not want. People always say "bitcoin has a hard coded, guaranteed limit of 21 million coins".
However, I think the limit of 21 million is subject to the consensus of the users and miners?
So if a consensus is formed to allow more than 21 million Bitcoins to be generated, then it will be so, right?

So, there is actually no mathematical limit to the number of coins. It's just that the issuance of coins is not subject to a central authority, but requires a supermajority consensus.

It is actually a modifiable feature of Bitcoin. If somebody has his/her own fork from Bitcoin, he/she can change it to a value whatever he/she likes. But the most important part here is whether the people will want to use that version of Bitcoin or not. So I don't expect that kind of a change happen in the future.
In our opinion, cloud mining is the most convenient way for it.
Cloud mining is the best way to lose money, don't fool people with false promises because you won't do well on this forum - we know it is 100% SCAM.

Everything is subject to change, but as others have commented, anything that would interfere with the basic features would actually be the creation of a new coin - and the original Bitcoin should just stay at its max supply, so Satoshi determined, and it should be respected. If you want to see what happens to alternative BTC that have a max supply of tens of billions best to take a look at all the BTC forks -> https://forkdrop.io/list-of-bitcoin-forks
No matter what, the original will always be what people follow the most - it is the only decentralized solution in the literal sense of the word - all other crypto projects have someone who manages them in their own interest.
if the consensus is considered as one of the benchmarks to support the 21 million Bitcoin numbers, then how can we clearly describe it that until now no one has tried to do this?
It is not. Your full node should have the code that enforces the specific parameters pertaining to Bitcoin's rules. You can verify that you are infact enforcing the 21 million rule by checking the rewards halving, difficulty re targeting and block rewards within the code.It is easy to change the parameters, whether anyone wants to follow your fork is an entirely different issue.
Whether with the amount of 21 million or not, bitcoin is beyond the control of any party, except for China, which seems to have the capacity to try to change the consensus system and make reforms. but in essence if the 21 million amount can be manipulated, then would you please give us a scheme to use?
They don't. Seems absurd that you think Bitcoin is within a control of any single entity and is still surviving at this point. 
It's just that the issuance of coins is not subject to a central authority, but requires a supermajority consensus.
Yes and no. A bitcoin node sends and receives information, but most importantly verifies. Note that each one runs autonomously. By that you understand that no one forces none to change a consensus rule, like the 21,000,000 coins. The already existent nodes define that Bitcoin works that way, since January of 2009. Every bitcoin node follows the rules chosen by satoshi. Everyone is free to change the consensus rules and continue/restart the blockchain, but that wouldn't be Bitcoin's. It would be a hard fork, a chain with different rules.To answer you, if the majority of the nodes decide to follow different rules, they immediately stop being the majority. But since it's a majority of users (which means that they're a lot), they can manipulate people that their Bitcoin is Bitcoin.

What does China have to do with the consensus rules of Bitcoin? The capacity has nothing to do with the consensus, not to mention that China isn't a single entity to perform 51% attack if we assume that they have enough computational power in total. 
One of Bitcoin's main strengths is it's historically unchanged and predictable supply schedule, as well as the max supply cap. You do realize though that changing the max supply totally invalidates this core characteristic, right? Not a single Bitcoiner in the right mind would support such change.

If you were to modify your Bitcoin Core with a different block interval, different block rewards or halving, you'll effectively change the total possible coins generated. This would only apply for those that is running the client with the same modification as you. So no, anyone can change the limit but it won't be followed. It is already happening with the altcoins that are forked from Bitcoin. The consensus that you've mentioned effectively means that those who runs that modification consider theirs as 'Bitcoin'.
As with the limit of 21 million, it'll probably not be called Bitcoin because there really isn't any real reason for it to be changed. The original Bitcoin should still have 21 million as its limit.
