Rename OpenSearch REST common module

[trask]

Part of

• Tracking package and module name alignment #18428

[Copilot]

Pull request overview

This PR renames the shared OpenSearch REST “common” instrumentation module to a versioned module (opensearch-rest-common-1.0) and aligns the shared helper package names accordingly, as part of broader module/package name alignment work.

Changes:

• Renamed the Gradle projects from opensearch-rest-common to opensearch-rest-common-1.0 and updated all project references.
• Moved shared javaagent helper classes into a versioned package (...rest.common.v1_0) and updated imports in the REST 1.0/3.0 instrumentations.
• Introduced a dedicated testing subproject for shared OpenSearch REST test utilities.
