pdksync - (GH-cat-11) Certify Support for Ubuntu 22.04

In Ruby 3.0 net-ftp changed from a bundled gem to a default gem. This
means it may not be available, such as when running unit tests.

Since ftp is becoming less and less common, this changes net-ftp to be
an optional dependency. Users who do need ftp support should ensure the
gem is installed.

Prior to this commit the title parameter of this defined
type was not properly validated. This means that it could have been
possible to use a resource title outside of the normal bounds of
a package name.

Additionally the `onlyif` and `command` parameter values were
interpolated strings meaning that it may have been possible to
execute unsafe code on the remote system.

This commit fixes the above issues by adding a regex to check that the
resource title is a valid apt package name and also breaks out the
`onlyif` and `command` parameter values in to arrays of args ensuring
that the commands executed in a safe manor on the remote system.

The exception in this commit is the `unless_cmd`. This has not been
broken out in to an array of args due to the requirement of the command.
This is a reasonable trade of however due to the fact that action is
created from known enum values and title would be pre-validated.
This is also explained in mark.pp:20.

This commit adds additional spec tests for mark.pp.

The tests validate the new resource name requirements
introduced in the previous commit.

Deal with net-ftp being unavailable

Prior to this commit there was a possibility that malformed strings
could be passed as the resources name. This could lead to unsafe
executions on a remote system.

This was also a possibility for the options parameter as it was
constrained to a string.

In addition, commands were not properly broken out in to arrays of
arguments when passed to the exec resource.

This commit fixes the above by adding validation to the resource name
ensuring that the given ppa name conforms to expectation. Also, commands
are now broken down in to arrays of arguments appropriately. This ensures
safer execution on the remote system.

Given that the options parameter, passed as a raw string, could lead to
unsafe code execution it was reasonable to change the accepted type to
an `Optional[Array[String]]. This means that an array of options can now
be passed to the exec resource inside the original command.

This commit adds spec tests that validate the changes made in
the previous commit.
