CI: some tests are unnecessarily skipped when run against Scylla

[muzarski]

A simple example are tests for duration cql type:

[SKIPPED] Unsupported for Apache Cassandra Version 3.0.8: Server version 3.10+ is required
[OK]      CassandraTypesDurationTests.Integration_Cassandra_MixedValues (1937 ms)

When scylla cluster is set up via ccm (no matter the version of scylla), the ccm <node> version command always returns a 3.0.8 version. This version is probably hardcoded in nodetool (ccm <node> version command delegates it to nodetool). However, there is a way to print a scylla version using ccm. There is a ccm <node> versionfrombuild command which seems to display the correct version of scylla node.

We need to adjust the logic responsible for filtering out the tests based on Scylla/Cassandra version. Testing framework should be aware whether it's used against Cassandra or Scylla cluster, and then execute either ccm <node> version or ccm <node> versionfrombuild respectively. Minimal versions required for specific tests should be adjusted for scylla, because I believe that there is no 1:1 mapping between Scylla's and Cassandra's versions and some features were probably introduced in different versions.
