Convert GPG public key to base64 on Salt Master

	$ # Problem:
	$ # * Official Debian GNU/Linux AMIs don't have gpg pre-installed.
	$ # * We want to bootstrap a host using a salt-cloud deploy script.
	$ # * This will add the key to the new host to add the Salt repository.
	$ # * We cannot use apt-key so must add the gpg binary into trusted.conf.d
	$ # directly.
	$ # * We can base64 encode (base64 command is part of coreutils)
	$ # but ideally won't store the key base64-encoded in pillar.
	$ # Solution:
	$ # A) Run `apt-get update`, install GnuPG, add the Salt repo key,
