Bug description:
[ Impact ]
The new apparmor profile for esm-cache.service has sub profiles for
subprocesses and some of them were incomplete, resulting in the
following apparmor DENIED messages in the following situations:

[ Test Plan ]
These were caught by the automated verification tests for v32.1 in
-proposed. If all of the automated verification tests pass for the
version with this fix (32.2), then that will be considered a
verification for this bug as well.
The specific tests that found this issue can be run with the following
command:
tox run -e behave -- -D install_from=proposed
features/attach_validtoken.feature:194
features/attach_validtoken.feature:196
[ Where problems could occur ]
The fix edits the template for the ubuntu_pro_esm_cache apparmor
profile. If mistakes were made, it may cause new apparmor denials or
other related issues, ultimately meaning esm-cache.service wouldn't
run properly, preventing esm update notifications from being displayed
on unattached machines.
