Windows: Sync hosts dir with proper permissions

[fullyint]

To run Ansible commands directly, Windows users have had to adjust permissions for files in the synced hosts directory. This PR implements @QWp6t's approach of syncing hosts with the proper permissions.

I bumped the Vagrant requirement to 1.8 to take advantage of the shell provisioner's new env option which enables us to pass the ANSIBLE_PATH_ON_VM to windows.sh.

Could a Windows user test and confirm that this works?

This PR simplifies the command at the end of windows.sh:

- ansible-playbook ${ANSIBLE_PATH}/dev.yml -i ${TEMP_HOSTS}/development --sudo --user=vagrant --connection=local
+ ansible-playbook dev.yml

• can use relative path to dev.yml because script already changed to that directory
• -i - can use default hosts file now that hosts are synced into place with the right permissions
• --sudo - already indicated as play parameter in dev.yml
• --user=vagrant - already indicated as play parameter in dev.yml
• --connection=local - I moved this to hosts/development which is only used for Windows anyway

This PR originally synced the hosts directory over the top of the vm's hosts directory, just so it would have specific mount_options (i.e., no execute bit set for hosts files). The latest commit removes that sync folder and instead applies these mount_options to the primary vagrant sync folder that is already there.

Doesn't this mean that deploy.sh won't execute now?

@QWp6t correctly pointed out that mount_options: ['dmode=776', 'fmode=664'] on the primary vagrant sync folder would cause deploy.sh to not execute. I added a commit switching back to the approach of syncing the hosts directory with the needed permissions.

Just tested this. It works. 👍
