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.

Everything was wrong here, wrong file used, wrong cleanup procedure, the net
result is this (and some failing tests from time to time):
$ ls -l /tmp/test_bolt_db* | wc -l

If an oracle node is resynchronized from the genesis the service receives all
requests from all blocks via AddRequests() invoked from the native
contract. Almost all of them are long obsolete and need to be removed, native
oracle contract will try to do that with RemoveRequests() calls, but they
won't change anything.
So queue up all "initial" requests in special map and manage it directly
before the module is Run() which happens after synchronization
completion. Then process any requests that are still active and work with new
blocks as usual.
