Update Prysm client to require 40k Boa stake as defined in Bosagora whitepaper.

[MichaelKim20]

The minimum staking amount required to become a validator is 40,000 BOA in the white paper of BOSAGORA.
We need to modify the code according to this.
The Beacon chain has a number of implementations.
First of all, we use prysm.

We can use this constant in the config.file and the value of 32e9 gwei(= 32 eth) is set to the constant in the source code.

MaxEffectiveBalance       uint64 `yaml:"MAX_EFFECTIVE_BALANCE" spec:"true"`       // MaxEffectiveBalance is the maximal amount of Gwei that is effective for staking.

I have changed the MaxEffectiveBalance to 40000e9 in the two config files, minimal_config.go and mainnet_config.go for this issue.
We should pass the unit tests for the change. So, I'm working on the errors on unit tests.

After the above change, we should change this line in the deposit-contract/scripts/staking.ts file.

We have to check this out, too. https://github.com/zeroone-boa/deposit-contract/blob/1ddcecf590e8be9aeeda1897cf339125e12b1f79/contracts/deposit_contract.sol#L113-L115
We need to check why Ethereum's minimum staking amount is 1 Ether.
Why should there be a minimum amount separately?

What is MinDepositAmount , Ejection Balance, Effective Balance Increment?
What should we do with their value?

[MichaelKim20]

There seems to be something to change in the code of the repository below.
I'd appreciate it if you could check.

OK, I will. And besides that, I will change the ether and gwei to boa and cent in all the related source code as a separate PR.

Right, I also thought the constant should be researched. At the moment, I think that the deposit could be done several times with the minimum amount. I will leave the result of the research.

As suggested here by @hewison-chris, We could set the MAX_EFFECTIVE_BALANCE to like 400K(the more proper value could be set later) and also MIN_DEPOSIT_BALANCE to 40K, which makes us give as much rewards to validators based on the amount of their deposit. I will consider how to apply it after confirming there is no problem with setting MAX_EFFECTIVE_BALANCE to 40K at first.

We learned the following from Jay's research.
We found out that we can solve this value by modifying the parameter in Prysm.
And this value, which is scattered in various repositories, will proceed with the revision of the project.

Then I'll close this issue.
