Delete public commit queue to avoid confusion after move to internal repo

commit-queue/README

-Commit queue master process scripts.
-
-This script requires privileged access to be able to impersonate svn
-credentials. When it detects it's not run on the main server, it will run in
-'dry run' mode where it has no effect; it doesn't modify issues on rietveld or
-commit patches.
-
-
-Design overview:
-
-The commit queue process runs a tight loop that does 2 things in parallel:
-- Scans for new reviews on a rietveld instance with commit bit (c+) set and
-  enqueue these to the commit queue.
-- Manages the pending entries in the commit queue by testing each item
-  independently and committing as soon as all the signals for a specific review
-  are green.
-
-The life of a pending commit is:
-- If any of the following steps fail; mark the review c-, remove from the queue
-  and add a comment on the review.
-  - Run presubmit scripts and make sure there is a LGTM from a valid reviewer.
-  - Send the patch to the try server on relevant builders and run relevant
-    tests.
-  - Wait for all try jobs completes and be green.
-  - Sync local checkout to HEAD.
-  - Apply the patch.
-  - Commit as the user.
-
-Each verification step is done through a Verifier plug-in. Every Verifier is a
-single python file in verifications/.
