Objective

Deploy a Ganache node on LocalNet to support E2E testing for the utility module. More specifically #869

Origin Document

#869 needs either A) addition of a endpoint+secret to the repo and deploying this pair as the servicer configuration, or B) a development/testing relay chain node, e.g. Ganache:

Goals

• Automatic deployment of a test node, i.e. which allows setting accounts/balances/etc., as part of LocalNet deployment. This node's service URL should be accessible from all pods running on LocalNet.

Deliverable
