renames the variants of the `blockqueryresponse` enum in the `queries.rs` file of the `localstate` miniprotocol.

the following changes were made:

- `getledgertip` is now `ledgertip`
- `stakepools` is now `currentpparams`
- `getcurrentpparams` is now `proposedpparamsupdates`
- `getproposedpparamsupdates` is now `stakedistribution`
- `getstakedistribution` is now `genesisconfig`
- `getgenesisconfig` is now `debugchaindepstate`
- `getrewardprovenance` is now `rewardprovenance`
- `getstakepools` is now `stakepools`
- `getrewardinfopools` is now `rewardinfopools`
this has been an attempt to map the server requests into our responses.

tests must be updated.
we added the struct. maybe we should adapt to use it as turbofish
- changed the argument of the `do_localstate_query` function from `localstate::queries::request` to `request`
- updated the function call in `main` to use `request` instead of `localstate::queries::request`
- removed unnecessary impls for `epochno`
