Fix last column alignment when more than 1000 items are listed in a cta-admin command output (#1014)

[repack] The expansion of a repack request will fail if there is no archive route configured to archive the files to repack on a tape

cta-verify-file command now gets instance, request.user and request.group from the command line instead of /etc/cta/cta-cli.conf

Leftovers from intermediate implementation

This commit adds a check for a requester mount policy with the hardcoded
name "default". Requester mount rule with this name must be present on
eoscta instance to pass this check

This is now handled client-side.

Improved human readability by correcting the order of the ORA error codes in OcciStmt::connShouldBeClosed()
