Suppress vagrant-hostsupdater

[QWp6t]

Since we're using vagrant-hostmanager, we can safely suppress vagrant-hostsupdater to prevent duplicate hosts entries when users have both plugins installed.

This is untested, but it's consistent with their documentation.

[QWp6t]

Just tested it. It works.

==> default: Checking for host entries
==> default: Skipping adding host entries (config.vm.network hostsupdater: "skip" is set)

So this is to prevent hostupdater from doing anything if it's already installed?

[QWp6t]

Yeah, exactly. vagrant-hostsupdater automatically updates hosts files regardless of whether your Vagrantfile explicitly tells it to. This PR opts out of it.
