Removes '--master' param from security rake tasks
What does this MR do?
Removes 'merge_master' from security rake tasks
- Since we now merge MRs in batches, the 'merge_master' param is now deprecated, so this commit is removing it.
-
MERGE_MASTER_SECURITY_MERGE_REQUESTS
was removed as well. - Also, it updates the security tasks section in our docs to reflect so
