RPC changes for protocol Q (part 1)

[dsawali]

Protocol Q brings about a list of RPC deprecation

All strikethrough'd bullet point will NOT be implemented

Disclaimer, the path ../ will be short for /chains/<chain_id>/blocks/<block_id>/context/delegates/<baker_pkh>/

Renames:

• GET ../current_frozen_deposits is renamed to GET ../total_staked, the old path is deprecated
• GET ../total_delegated_stake is renamed to GET ../external_staked, old path is deprecated
• GET ../current_baking_power is renamed to GET ../baking_power, old path is deprecated
• GET ../delegated_contracts is renamed to GET ../delegators, old path is deprecated
• GET ../full_balance is renamed to GET ../own_full_balance, old path is deprecated
• GET ../unstaked_frozen_deposits is renamed to GET ../total_unstaked_per_cycle, old path is deprecated

Additions:

• Added GET ../total_delegated endpoint, which returns the amount that counts as delegated to the baker for the purpose of computing its baking rights. This includes tez owned by all delegators including the baker itself, but excludes staked tez (MR: !14176)
• Added GET ../external_delegated, which returns the amount of non-staked tez owned by all delegators except for the baker itself. (MR !14187)
• Added GET ../own_staked and GET ../own_delegated, these are similar to total_staked and total_delegated, except they only consider tez owned by the baker itself

Deprecations (only):

• Deprecated RPC GET ../staking_balance. Staking balance value can now be obtained by adding values of GET ../total_staked and GET ../total_delegated together
• Deprecated RPC GET ../delegated_balance, Delegated balance value can now be obtained by adding values of GET ../external_staked and GET ../external_delegated together
• Deprecated RPC GET ../delegated_balance. To get its value, you can call GET ../total_staked on the last block of 3 cycles ago.
• Deprecated RPC GET ../frozen_deposits_limit, currently irrelevant since activation of AI and staking

Currently, in taquito rpc package we only support two endpoints with path /chains/<chain_id>/blocks/<block_id>/context/delegates/<baker_pkh>/
one is getDelegates - /chains/<chain_id>/blocks/<block_id>/context/delegates/<baker_pkh>/
the other is getVotingInfo - /chains/${this.chain}/blocks/${block}/context/delegates/${address}/voting_info
So the above renames and deprecations is not relevant to taquito in q development.
As for additions we usually don't support baker related rpc assuming they'll use octez-client instead.
Unless you see significance of adding them now, we can discuss
