Code review

No issues found. Verified this is a faithful backport of upstream commit 59ad0a1 (HDDS-14104, #9493) to ozone-2.1:

• All 5 files in PR HEAD 9906194 end at the same blob as upstream master post-merge (RequestContext.java → 44e0f928; the 4 test files have identical blob SHAs to upstream).
• The cherry-pick conflict in RequestContext.java was caused by the HDDS-13753ipc → ipc_ import rename being present on master but not on ozone-2.1. Resolution is correct: HDDS-14104 deletes both the import and its only caller (getBuilder(ugi, aclType, ownerName)) entirely, so the package-name divergence is moot.
• All callers of the removed APIs (new RequestContext(...), new RequestContext.Builder(), getBuilder(...)) on ozone-2.1 are tests, all updated by this PR. No production callers are left broken.
• All reviewer feedback from upstream PR HDDS-14104. Refactor RequestContext creation #9493 is preserved in the backport.
