In the case where importing the cert and key removes the files from disk
the existing deploy will fail when it tries to remove those files. This
still attempts to remove the files but catches the error and moves on instead
of bombing like before.
Similarly, if the deploy had failed before, subsequent deploys would fail
because the script already existed, so it would not be able to create
the script. This first attempts to remove the script if it exists, and then
creates the script.
when fetching all zones the memory usage can exceede limits and also
cause timeouts.
with this change the zone will be searched via the longest to shortest
match using the get endpoint.
it is related to this bug report: opnsense/plugins#3525
FreeBSD's sed doesn't have the -z option, so empty certificates are delivered to vault when running the script on FreeBSD.
