Revamp Dockerfile for more modern deployment
This commit makes several updates to the Dockerfile meant to align it
more closely with the way we typically deploy RT today. Goals are:
* Upgrade to Debian 10.
* Build our own Perl from source to test with.
* Install RT's dependencies from CPAN rather than Debian.
* Make it easy to retrieve that list of modules, and their versions,
for further testing, development, and deployment.
* Make it easier to update this Docker image and keep it modern.
Steps are:
* Parameterize the main parts of the build that vary, like Perl version
and RT's cpanfile, with build arguments. This lets you test new things
with `docker build --build-arg` rather than updating the Dockerfile.
* Add steps to download and build Perl from source, including
workarounds for known test oddities (documented in comments).
* Install RT's dependencies by running `cpm` against RT's `cpanfile`.
This lets the Docker image stay up-to-date with changes in RT's
dependencies automatically, and as a bonus makes the build faster.
* Provide a CMD that prints out a CPAN autobundle. After you build the
image, you can `docker run` it to save this information for use
elsewhere.
