Moves configured integrations and session storage to new service

[axosoft-ramint]

Major refactor (and fix to Home View integration states) that does the following:

• Creates a new configuredIntegrationService
• Moves all management of stored integration configurations as well as stored integration authentication sessions to the new service
• Renames functions across auth providers and the new service to be clearer, and simplifies logic on the integration authentication providers where possible
• Adds domain property to integration auth sessions
• Removes redundant code that isn't used, and makes a session descriptor required when interacting with an auth provider
• Updates home view to use the new service to get configured integrations

We will want this in before adding other cloud integrations into the mix, like Azure.

@axosoft-ramint

quick question. Which domains are "ours"? those that are stored in configuredIntegrationService?

[axosoft-ramint]

"Ours" are the ones we have locally stored and configured, as you guessed. While the other domain being compared here is the one returned by our api for the provider.
