Standard Tests: allow specifying exact record matches

Tell us about the problem you're trying to solve

standard tests are currently smoke tests which don't allow verifying that exact records were produced. We want to have this functionality so we can write more robust tests.

[keu]

for this we should provide files with expected records,
test options are:

Options	Default Value	Meaning	Estimation
exact_order	False	Ensure that records produced in exact same order	2h
extra_fields	True	Allow records to have other fields	1h
extra_records	True	Allow connector to produce extra records, but still enforce all records from the expected file to be produced	1h

by default test configured to be as much flexible as possible.

base implementation - 2h
Total dev estimation - 6+h

some initial match was implemented in the first version of Standard Tests. All options were added by they are NOP
