GitHub Actions Integration Tests

Description of the Change

This introduces CF CLI integration tests

[a-b]

I propose to have workflow names use shared namespace-like prefixes. For example

Current	Proposed
.github/workflows/setup-cf-env.yml	.github/workflows/cf-env-setup.yml
.github/workflows/unclaim-cf-env.yml	.github/workflows/cf-env-unclaim.yml

Chatted with @ccjaimes about this. The integration tests are now running. There are some test failures, but we think there is value in getting this merged so we can start seeing if tests are flaky and how we feel about the tests running here. We don't think these integration tests should be a blocker to merging PRs until we fix the known test failures. We'll start opening other PRs to fix the test failures.

Here's a list of the test failures we've seen so far

• route_sharing feature is not enabled by the tests that need them
• src/code.cloudfoundry.org/cli/integration/helpers/fixtures/fifty-spaces-org.json is a hard coded path in some tests
• some tests failed at using isolation segments

Once those test failures are addressed, then we can make passing the integration tests a blocker for PRs

If things go really wrong, we can always roll back or disable these integration tests cc @cloudfoundry/wg-app-runtime-interfaces-cli-approvers & @cloudfoundry/wg-app-runtime-interfaces-cli-reviewers for comment
