Deploy Vault and Salt master on Complector

Summary:
Complector is a dedicated host for Vault and Salt master.

It's not reachable directly from InterNet, you need to use
a bastion, a development server for example, to access it.

It's currently a VM on dreadnought, so it uses the Intranought network.

Ref T1702.

Test Plan: Apply core role on Complector
