[DISCUSS] KNOX-1608: Remove gateway-adapter compatibility module in 3.0.0

Hi team,

I would like to start a discussion regarding the removal of the legacy
gateway-adapter module under KNOX-1608.

PR #1263 removes the gateway-adapter module, which has been shipping
@Deprecated-since-0.14.0 shims in the org.apache.hadoop.gateway.* package
that pure-delegate to their org.apache.knox.gateway.* counterparts.

This is a source-compatible but binary-incompatible change for anyone still
referencing the old FQCNs in topologies, provider configs, or downstream
code. Since 3.0.0 is already a breaking release (JDK 17 baseline), this is
the natural window to remove them.

Please let me know if there are any objections, questions, or feedback
regarding purging this legacy module for 3.0.0, please reply here before we
merge.


Best regards,

Arun
