Claim reward updates

[liberumed]

Motivation

Stakes snapshotting in the contract takes time and resources so it was decided to move it as part of the explorer app in blockscout so we can store snapshotted data in Postgress DB and populated it to the user differently.

Also, some contracts functions and events were removed or renamed so we need to update ABI as well.

This branch is working with https://github.com/poanetwork/posdao-test-setup repo.

Changelog

• Rename contract functions
• Rename contract events
• Delete contract functions
• Add fields to StakingPool and StakingPoolsDelegator required for stakes snapshotting
• Remove chain based stakes snapshotting porcess
• Add blockscout based stakes snapshottting process
• Display “Accounted Stake Amount” and “Current Reward Percent” in delegators list

TBD

• Implement Frontend for validator info
• Check function that have changed implementation
• Chechk consequences from removing update_tokens process

💛 - Coveralls

[varasev]

Now I think we can merge this to the staking branch. Once merged, I will retest the app based on the staking branch and fix new issues (if any). After that, before merging staking to master, I'll make final UI fixes that were postponed (partially listed in https://github.com/poanetwork/blockscout/issues/2850).

@varasev ci/circleci: dialyzer test is failed. It would be awesome to fix it before merging. Please, let me know if you want from me to take a look.

[varasev]

@vbaranov Yeah, I see - tried to fix the line in .dialyzer-ignore: 3561943

[vbaranov]

I think it is ready to be merged now 👍
