4.x: Allow arbitrary Scylla versions in CcmBridge

[Bouncheck]

Until now, the versions passed through ccm.version property would be considered invalid if cannot be parsed to one of the known formats. Now if the parsing fails, the property will be passed to ccm commands "as is" which ccm will treat as directory name in local repository. Numbered version will then be fetched through setting up a makeshift cluster and asking ccm for it.

[Bouncheck]

Verified by passing 6.2.0 as "abc123" through IDE. Same effect as:

$ cp -r ~/.ccm/scylla-repository/release/6.2.0 ~/.ccm/scylla-repository/abc123
$ mvn clean verify -Dtest=MetadataIT -Dccm.version=abc123 -Dccm.scylla=true -Dsurefire.failIfNoSpecifiedTests=false

Example result
