Issue #1375: Allow /vagrant synced folder to be overridden

[oxyc]

How about leveraging the same logic as we already use for vagrant_synced_folders?

vagrant_synced_folders:
  - local_path: .
    destination: /var/www/drupalvm
    type: nfs
    create: true
  - local_path: .
    destination: /vagrant
    type: rsync
    options_override: [...]

Would need to add docs for this though.

Looks good to me; don't know if we need docs on it? Maybe in the Linux section, a note about adding override options if you hit slowness...

[oxyc]

👍 tomorrow I'll add a note in the linux section and run some tests to verify that it works as expected.

@oxyc ++ thanks for running with it! I'm knee-deep in some other automation projects currently, but will try to get some time for a few more of these interim improvements while Drupal VM 4.5.x simmers a bit.
