Availability check for Vagrant connector

[ssmirr]

At the moment Vagrant connector is not able to run availability checks on VMs because of missing getContainerIp(...) function:

opunit/lib/inspect/checks/availability.js

Line 14 in 6d76470

let ip = await this.connector.getContainerIp(context);

This function should just return the ip address for the VM, for an example see this function in Baker connector:

opunit/lib/harness/baker.js

Lines 43 to 51 in 6d76470

	async getContainerIp(context)
	{
	let doc = await this.getOrLoadBakerYaml(context);
	if( doc.vm && doc.vm.ip)
	{
	return doc.vm.ip;
	}
	throw new Error(`No ip defined in baker file in ${context.bakerPath}`);
	}

I think the best way to get the IP of the Vagrant VM is to parse Vagrantfile:

config.vm.network "private_network", ip: "192.168.33.10"

In addition to adding getContainerIP(), updating setup() and tearDown() are needed.

For availability check to fully work for Vagrant and Ssh connectors, a tearDown() is needed. Job of this function is stop the server after availability check's work is done. I'm closing this issue and creating a new one for tearDown() to include more details.
