apt_repository needs dirmngr installed

[palfrey]

Cookbook version

6.1.4

Chef-client version

13.7.16

Platform Details

Debian Stretch

Scenario:

Adding new apt_repository

Steps to Reproduce:

I was using nodejs::repo (https://github.com/redguide/nodejs/blob/master/recipes/repo.rb) but anything that uses apt_repository on a fresh Debian Stretch box will fail similarly. Note that this doesn't work on your current Travis tests, as the Dokken Docker Stretch box installs dirmngr (https://github.com/someara/dokken-images/blob/master/debian-9/Dockerfile)

Expected Result:

New apt repository added ok

Actual Result:

Relatedly, there's https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=845720 but upstream has marked it as "wontfix" for some reason.

I think its reasonable to add the package to be installed in the default recipe. Not sure how the other maintainers feel but I can certainly agree with the debian maintainer that gpg can be run without dirmgr as it is only needed if you are using a nework. As this repo/cookbook clearly takes the stance that you have a network to add keys from I think we should add it here.
