apt:🔑 Redo apt::key, make it use apt_key.

Introducing a totally rewritten and tested apt::key. This commit also
patches the spec's of apt::source because it was passing in data that
is no longer allowed by the new validation rules in apt::key.

It does its best to not touch any other specs and where we touch them
only minimally to ensure that we're not introducing breaking changes.

# == Define: apt::key
#
# The apt::key defined type allows for keys to be added to apt's keyring
# which is used for package validation. This defined type uses the apt_key
# native type to manage keys. This is a simple wrapper around apt_key with
# a few safeguards in place.
#
# === Parameters
#
# [*key*]
# _default_: +$title+, the title/name of the resource
#
# Is a GPG key ID. This key ID is validated with a regex enforcing it
# to only contain valid hexadecimal characters, be precisely 8 or 16
# characters long and optionally prefixed with 0x.
#
# [*ensure*]
# _default_: +present+
#
# The state we want this key in, may be either one of:
# * +present+
# * +absent+
#
# [*key_content*]
# _default_: +undef+
#
# This parameter can be used to pass in a GPG key as a
# string in case it cannot be fetched from a remote location
# and using a file resource is for other reasons inconvenient.
#
# [*key_source*]
# _default_: +undef+
#
# This parameter can be used to pass in the location of a GPG
# key. This URI can take the form of a:
# * +URL+: ftp, http or https
# * +path+: absolute path to a file on the target system.
#
# [*key_server*]
# _default_: +undef+
#
# The keyserver from where to fetch our GPG key. It defaults to
# undef which results in apt_key's default keyserver being used,
# currently +keyserver.ubuntu.com+.
#
# [*key_options*]
# _default_: +undef+
#
# Additional options to pass on to `apt-key adv --keyserver-options`.
