Cliff Parsons 1da7a5b0f8 Fix problems with DB utilities in HTK and Postgresql
This PS fixes:
1) Removes printing of the word "Done" after the restore/list command
   executes, which is not needed and clutters the output.
2) Fixes problem with list_tables related to command output.
3) Fixes parameter ordering problem with list_rows and list_schema
4) Adds the missing menu/parameter parsing code for list_schema
5) Fixes backup-restore secret and handling of PD_DUMPALL_OPTIONS.
6) Fixes single db restore, which wasn't dropping the database, and
   ended up adding duplicate rows.
7) Fixes cronjob deficiencies - added security context and init containers,
   fixed backup related service account related typos.
8) Fixes get_schema so that it only finds the table requested, rather
   than other tables that also start with the same substring.
9) Fixes swift endpoint issue where it sometimes returns the wrong
   endpoint, due to bad grep command.
