Add error checking before creation and deletion

Describe the feature you would like to see.

The current approach in Convoy fires off a job to create and delete a virtual machine. This has the advantage of speeding up the creation and deletion process. However, if a deployment fails, then it is not possible for an application such as WHMCS or Blesta to find out about it unless they are polling Convoy and constantly checking the status. For example, if a host node is down and Convoy tries deploying a VM on it, that VM will be fail to install but WHMCS would mark it as provisioned since Convoy returns no error through the API.

Describe the solution you'd like.

Convoy should run tests to make sure that the virtual machine can deploy before deploying the machine. If it detects that it cannot deploy a virtual machine for some reason (i.e., node is offline, template is not on the destination node, etc), then it should not. It may not even be necessary to fire off the creation or deletion process as a job.
