logs v4 qb refactor

[nityanandagohain]

For #5555 , second PR . Follow up of #5872

Changes made code wise

• In v3 folder json_filter.go , json_filter_test.go, query_builder.go
  Some functions and constants are made public in these files and no other change.

• In v4 folder json_filter.go and json_filter_test.go
  The only change for these two files is that the map jsonLogOperators uses LIKE instead of ILIKE. So the function GetJSONFilter is a local one and no change apart from that.

• In v4 folder query_builder.go and query_builder_test.go

  • It adds the resource filter caluse
  • new select clauses for map support.
  • refactoring the code as we did for v4 resource qb
  • Only body contains search is case insensitive

Can we get rid of v3 in logs after v4 is fully rolled out?

[nityanandagohain]

Yeah once it is fully rolled out, we will stop ingestion for the old table and the entire v3 code can be removed, some functions will have to be moved to the new folder that we are reusing.
