txsource/queries: workload doing various queries

[ptrus]

Queries workload, part of: #2506

• Also removes GetNodeList() client query as it's almost identical to the GetNodes one (minus the sorting) and it's not used anywhere at the moment - can revert that commit if desired. (extracted out)
• adds LastBlockFees query method to staking client, so that client is able to obtain all funds and confirm total supply matches correctly

Feel free to comment in case any relevant queries/checks should be added.

TODO:

• bunch of todos in code
• requires txsource: runtime workload #2759 merged in

weird, why did we even have both?

[pro-wh]

also, are we testing these?

[kostko]

Slightly unrelated, but this is also something that should be part of the genesis state dump as otherwise it could cause the total token amount to become inconsistent on dump/restore.

[ptrus]

oh we don't do that at the moment :o will do a PR that adds that tomorrow 😁

[ptrus]

thanks for the reviews @pro-wh
