Suppress VAGRANT_EXPERIMENTAL warnings

[Hussam Qasem]

Greetings!

In my Vagrantfile, I have:

    ENV['VAGRANT_EXPERIMENTAL'] = 'disks'

This causes the following (annoying) warning to be printed with every vagrant command:

    ==> vagrant: You have requested to enabled the experimental flag with the following features:
    ==> vagrant:
    ==> vagrant: Features:  disks
    ==> vagrant:
    ==> vagrant: Please use with caution, as some of the features may not be fully
    ==> vagrant: functional yet.

Anyway to suppress this particular warning?

Thank you!
