Prepare POT files for metadata.json summary and description

For showing the translations on the forge, all summary and description fields need to be extracted into POTs. Due to timing constraints (this goes out with the translated READMEs) we need to do so manually before the tooling is in place.

See https://github.com/puppetlabs/pe-razor-server/blob/11e3629d3e4e366a2e53b3be900fe87a22d7d11a/locales/razor-server.pot for an example.

For each of the target modules (list TBD) create the locales/en.pot with msgid entries for both the modules' summary and description from the metadata.json.

Modules in scope for this ticket:
NTP (consider this module as our beta)
Apache
MySQL
SQLserver
Stdlib
AWS
PostgreSQL
Tagmail
Tomcat
Azure

The process for creating the POT file is manual but filtering the summary and description can be filtered as built in functionality for the json2po tool
