CLI: Add ability to skip tests for status command

#### Is your feature request related to a problem? Please describe.

Yes. After the latest update, a hosting partner began experiencing a problem with the `test__server_port_value`. Specifically, the test was skipped properly when ran via CLI, but when ran via an endpoint that called CLI, the test failed. In this case, a workaround was to unset the SERVER values that the test looks for.

#### Describe the solution you'd like

it would have been ideal if the hosting partner could optionally skip the `test__server_port_value` or just skip all of the tests and test the connection alone OR if `Jetpack::is_active()` is true.

#### Describe alternatives you've considered

#### Additional context

Here's a screenshot of the skipped test that was shared with us.


It would be ideal if, along with `--skip-theme`, we could do something like `--skip-tests` or `--skip-test=test__server_port_value,test__outbound_http`.

Start at the status CLI command and inspect how the existing --skip-theme option handles tests. Compare the requested behavior for --skip-tests and selective skipping of test__server_port_value and test__outbound_http. Done means the status command can test only the connection or omit the requested tests without reproducing the reported failure.
