Request NEP17 balances from a set of NEP17 contracts instead of getting
them from storage. LastUpdatedBlock tracking remains untouched, because
there's no way to retrieve it dynamically.
Balances are to be removed from state.NEP17TransferInfo, so the remnant
fields are NextTransferBatch, NewBatch and a map of LastUpdatedBlocks.
These fields are more staff-related.
Also rename dao.[Get, Put, put]NEP17Balances and STNEP17Balances
preffix.
Also rename NEP17TransferInfo.Trackers to LastUpdatedBlockTrackers
because NEP17TransferInfo.Balances are to be removed.
It supposedly fixes some Windows and Solaris problem, but this commit is
deliberately taken before the package switches to Go 1.17 (as we still need
older versions).
We were using some version from 2018 and there was a big number of fixes
and optimizations since then. It's not managed well though, current 1.0.0 tag
is 2019, so we're using latest and greatest here.
Prometheus is somehow better (isn't noticeably probably), but it also
wants at least 2.3.0 YAML package, so update it to 2.4.0 which fixes some
important bug wrt v2 line (maybe we need to migrate to v3 though)/
We're only using queue library and it didn't change in any way, but 1.0.53 has
proper go.mod, so it's still an improvement.
It at the same time pulls some new packages also like x/tools.
It was broken somewhere between 2f490a3403 and
85ce207f40 leading to panic on watch only node:

In fact, nonce is correctly provided by dbft library (since Legacy), we just
need to use it here.
Implement a way to check if tx has been persisted on blockchain and
to get general info about transaction. Much more convenient than
handwritten curl queries.
