Backport VAULT-43691 - Fix SQL injection risk in HANA and Redshift DeleteUser revoke paths into ce/main (#14047)
* VAULT-43691 - Fix SQL injection risk in HANA and Redshift DeleteUser revoke paths (#13741)

HANA now safely quotes usernames as identifiers, and Redshift safely quotes
usernames as string literals before constructing revoke/delete SQL. Added
regression tests to ensure crafted usernames cannot inject additional SQL and
that only the targeted user is deleted.
