[Story] Configure Resource Processor to use Azure storage for Porter remote state

[marrobi]

Description

As a TRE developer
I want to be able to access the state of previous porter deployments
So that I can uninstall bundles.

Acceptance criteria

• Porter Azure plugin installed for Resource Processor
• Porter Azure plugin configured: Runner uses MGMT_STORAGE_ACCOUNT_NAME for porter state - https://github.com/getporter/azure-plugins (azure cli and MSI)
• Functionality documented in Resource Processor README

Currently Porter state is persisted on the VM within the scaleset. Will be lost.

@marrobi I think we talked about this plugin being very "fresh"... do you have an opinion about using an azure share instead?

[marrobi]

@tamirkamara The challenge with shares is that we are having to deploy bundles within bundles as Porter cannot pass parameters into dependencies:

getporter/porter#990

We also need to be able to uninstall these dependent bundles.

This means mounting the share to the the bundle, which I'm not sure is possible, I was planning to use the blob storage plugin once sorted at the base level (although haven't tested this).

Ideally the bundle dependencies would work and then it wouldn't matter.
