Subject: (PUP-10510) Fix sshkeys not being correctly purged

After adding support for composite namevars in version 2.0.0, the module
lost the ability to purge sshkeys. This happens due to Puppet being
unable to correctly match the names and types of the sshkeys to be
purged.

Part of the fix was done in
https://github.com/puppetlabs/puppet/pull/8174, which changes how a
resource is initialized if the provider implements a `title` method.

Additionally, we add the key name and type to be included in the output
shown by `puppet resource`.
