patch by absurdfarce; reviewed by absurdfarce and adutra for CASSANDRA-19352

The java driver uses netty channel attributes to decorate a
connection's channel with the cluster name (returned from
the system.local table) and the map from the OPTIONS response, both
of which are obtained on connection initialization.

There's an issue here that I wouldn't expect to see in practice in
that the AttributeKey's used are created using
AttributeKey.newInstance, which throws an exception if an
AttributeKey of that name is defined anywhere else in evaluated code.

This change attempts to resolve this issue by changing AttributeKey
initialiation in DriverChannel from newInstance to valueOf, which avoids
throwing an exception if an AttributeKey of the same name was previously
instantiated.

If an exception was thrown while getting new metadata as
part of schema refresh it died on the admin executor instead
of being propagated to the CompletableFuture argument.
Instead, catch those exceptions and hand them off to the
CompletableFuture.

…thub.com/apache/cassandra-java-driver into scylla-4.x-merge-4.18.1

Following conflict resolutions and additional changes were made:
- Version was changed to 4.18.1.0-SNAPSHOT
- deep-lic-scan.yaml was removed. Likewise we don't have a fossa subscription.
- added with modifications previously skipped distribution-source module.
  Changed groupId, versions and names.
- added with modifications previously skipped distribution-tests module.
  Changed groupId, versions and names.
- Skipped license-maven-plugin which was checking for ASF license headers.
- removed `<oldArtifacts>` section of revapi plugin configuration pointing to
  datastax.
- Skipped addition of maven-remote-resources-plugin (pom.xml).

- Switched Scylla specific uses of `AttributeKey.newInstance` to `.valueOf` too
- Added `WHERE key='local'` to `system.local` queries in `DefaultTopologyMonitorTest`
- Removed irrelevant to Scylla version of the driver parts of the documentation
- Merged in translation between older and newer variations of config keys
  and values.
- Discarded some adjustments for upstream's Jenkins setup which conflicted
  with adjustments for our CI.
- Added extra stubs in BasicLoadBalancingPolicyPreferredRemoteDcsTest
  to match Scylla's modifications.
