NetworkManager does not run the dispatcher.d scripts for DHCP network interfaces on the first up event

Prerequisites

• [x] Put an X between the brackets on this line if you have done all of the following:
  • Reproduced after disabling all Vagrant plugins you installed
  • Checked that your issue isn't already filed: https://github.com/scissor-project/open-scissor/issues

Description

During provisioning we create scripts for NetworkManager to run, but we don't restart NetworkManager.service after such scripts are put in place. For this reason those scripts are not executed when a network interface is configured via DHCP.

Host Environment

• Host operating system and version: Ubuntu 16.04
• Vagrant version: 2.0.1
• Hypervisor version: Virtualbox 5.1.30

Steps to Reproduce

1. vagrant up gateway
2. vagrant up kafka
3. vagrant ssh kafka
4. sudo journalctl -u NetworkManager-dispatcher

Expected behavior: see evidence of dispatcher.d scripts running

Actual behavior: scripts are not executed

Reproduces how often: always
