chore(embedded/store): lock-free WaitForTx and WaitForIndexingUpto implementation

[arturmelanchyk]

Using atomic is lock-free and in this specific case roughly ~50% faster than using mutex

Hi @tomekkolo @SimoneLazzaris
could you guys please take a look into this?

[SimoneLazzaris]

Looks good to me

Hi @SimoneLazzaris
I have updated the code to be able to compile with golang 1.17, workflow now should be able to run

[arturmelanchyk]

Hi guys,
unfortunately build fails to some coveralls error, not related to the code

bad response status from coveralls: 422
{"message":"Couldn't find a repository matching this job.","error":true}

@arturmelanchyk , please sign commits with GPG

[arturmelanchyk]

Ok, reabased onto latest master and signed commits with GPG. However, coveralls step still fails 🤔

[arturmelanchyk]

Just a kind reminder @tomekkolo @SimoneLazzaris , branch has been rebased onto latest master and all commits signed with GPG

looked once more, can you provide a benchmark showing the improvement and also using 64 bit is not needed here.
