Fail early if required dependencies fail

[k1sul1]

If Composer is not installed properly locally, weird behaviour may ensue. Example:

vagrant up
==> default: config.yml was not found. Copying defaults from sample configs..
Bringing machine 'wordpress-box' up with 'virtualbox' provider...
==> wordpress-box: Importing base box 'seravo/wordpress'...
==> wordpress-box: Matching MAC address for NAT networking...
==> wordpress-box: Checking if box 'seravo/wordpress' is up to date...
==> wordpress-box: Setting the name of the VM: redacted_wp_wordpress-box_1519038602133_64247
==> wordpress-box: Clearing any previously set network interfaces...
==> wordpress-box: Preparing network interfaces based on configuration...
    wordpress-box: Adapter 1: nat
    wordpress-box: Adapter 2: hostonly
==> wordpress-box: Forwarding ports...
    wordpress-box: 22 (guest) => 2222 (host) (adapter 1)
==> wordpress-box: Running 'pre-boot' VM customizations...
==> wordpress-box: Booting VM...
==> wordpress-box: Waiting for machine to boot. This may take a few minutes...
    wordpress-box: SSH address: 127.0.0.1:2222
    wordpress-box: SSH username: vagrant
    wordpress-box: SSH auth method: private key
==> wordpress-box: Machine booted and ready!
==> wordpress-box: Checking for guest additions in VM...
    wordpress-box: The guest additions on this VM do not match the installed version of
    wordpress-box: VirtualBox! In most cases this is fine, but in rare cases it can
    wordpress-box: prevent things such as shared folders from working properly. If you see
    wordpress-box: shared folder errors, please make sure the guest additions within the
    wordpress-box: virtual machine match the version of VirtualBox you have installed on
    wordpress-box: your host and reload your VM.
    wordpress-box: 
    wordpress-box: Guest Additions Version: 4.3.36
    wordpress-box: VirtualBox Version: 5.2

This happened because user didn't have Composer in their path. Composer is ran in the context of the users machine in order to use packagist.com token, and for performance reasons, it's simply unacceptably slow when ran in the context of Vagrant.

Kill the script early with a sensible error message instructing what to do. The Vagrant box has to be destroyed because it may be in a broken state.

Basically:

vagrant destroy
rm -rf .vagrant .vincit.d
