ci: redo cicd

[dkropachev]

Goal of the PR

1. Speed up CICD
2. Make every step to be easily reproducible locally
3. Separate build files from the code
4. Run integration tests on different versions of scylla and cassandra.

Pre-review checklist

• I have split my patch into logically separate commits.
• All commit messages clearly explain what they change and why.
• PR description sums up the changes and reasons why they should be introduced.
• I have enabled appropriate tests in .github/workflows/build.yml in gtest_filter.

CICD Speedup results:
Build + Scylla IT: takes 5 minutes instead of 18.
Build + Cassandra IT: takes 6 minutes instead of 18.

I see two main issues here:

1. The test binary cache is not working as intended - the binary is not found in the cache in Scylla ITs job, and then, it is built again.
2. Something is messed up with the test filter. Notice that we only ran 9 test cases - This is probably the reason why CI sped up so much. When it comes to the filter, I see some unnecessary whitespaces that probably mess things up:
   Note: Google Test filter = ClusterTests.* :BasicsTests.* :PreparedTests.* :CassandraTypes/CassandraTypesTests/*.Integration_Cassandra_* :BatchSingleNodeClusterTests*:BatchCounterSingleNodeClusterTests*:BatchCounterThreeNodeClusterTests* :ErrorTests.* :SslNoClusterTests*:SslNoSslOnClusterTests* :SchemaMetadataTest.*KeyspaceMetadata:SchemaMetadataTest.*MetadataIterator:SchemaMetadataTest.*View* :TracingTests.* :ByNameTests.* :CompressionTests.* :LoggingTests.* :PreparedMetadataTests.* :UseKeyspaceCaseSensitiveTests.* :-PreparedTests.Integration_Cassandra_PreparedIDUnchangedDuringReprepare :ExecutionProfileTest.InvalidName :*NoCompactEnabledConnection :PreparedMetadataTests.Integration_Cassandra_AlterDoesntUpdateColumnCount :UseKeyspaceCaseSensitiveTests.Integration_Cassandra_ConnectWithKeyspace:*_DSE_*

Thanks, now it looks good, please take a look.

Mostly some nits. Other than that, really nice job!
