Add tfe_github_app_installations Data Source

[zisom-hc]

Use-cases

I need to be able to reference all of the available github app installations through a single resource.

Attempted Solutions

No current solution to dynamically pull data about the currently configured GitHub Apps. The tfe_github_app_installation resource requires that you must specify identifying details about a particular GitHub App installation for it to obtain information.

Proposal

Name: tfe_github_app_installations
Argument(s):

• organization (optional) - If it's an HCP Terraform account
  • This one doesn't allow to TFE, but would be assumed from the provider configuration if not provided explicitly
• hostname (optional) - if it's a Terraform Enterprise installation (since GitHub Apps exist at the platform/admin level)
  • By default, this value would be assumed from the provider configuration

Attributes:

• Name
• GitHub App ID

This would greatly reduce the amount of tfe_github_app_installation data sources we need to have within our workspace onboarding module (1 for every workspace[1,000+]), which would result in significantly reduced plan operation times, and API calls made to HCPT/TFE.

Bumping this as it's still highly desired, and would be highly impactful to have implemented.
