[267] Add cross-workspace support to the Terra storage provider.

[giventocode]

Closes: #267

This PR includes:

• TerraStorageAccessProvider generates SAS tokens from any URL Azure storage container managed by Terra provided the user has access to it.
• The implementation in based on the following assumptions:
  • The storage container name contains the workspace id.
  • The storage account is a valid LZ storage account that follows its naming convention.
• Removed unnecessary logic to handle local paths as well as a "known" folders as this logic does not apply to Terra
• Added basic integration test infrastructure for Terra.
  • These integration tests are disabled.
