Allen Porter d45501a129 Use shared envTest for unit tests 
Speed up unit tests by using a shared envTest. This requires each
test to use its own namespace to avoid clobbering objects for
other tests. Tests previously took around 8 seconds each, and now
the initial test takes 2 seconds with follow up tests taking less
than a second each.

Also update existing tests that use a fixed namespace to use a
generated namespace.

Share gold file template function with yaml files.

Remove the testClusterMode, and instead rely on MainTest to do
the appropriate test setup and rootArgs flag setup. Move the
rootArg flag setup out of NewTestEnvKubeManager to avoid
side effects.

A follow up change can be to push the individual setups
from NewTestEnvKubeManager() into their respective TestMain since
the harness share little code.

Allen Porter e8d6d5fe5c Remove fakeclient and use testenv for flux cmd tests 
Remove use of the fake client, and replace with a real client connected to the
testEnv.

This required fixes to the yaml files as the testEnv has stricter verifcation
of objects. This also meant it was not possible to test a GitRepository with
a missing artifact since that is not a valid state.

The tests are slower than before, taking around 7-10 seconds each because the
 testEnv is setup and destroyed for every test. These will be sped up in a
 follow up PR.

Allen Porter 351d287d88 Add tests for flux trace command 
Add tests for flux trace command that fake out the kubernetes client,
load objects from a yaml file and create them in the client, and
assert on the output of the trace command to an expected golden file.

This is a follow up from the suggestions in PR https://github.com/fluxcd/flux2/pull/1626 which suggested that additional
testing would be helpful. This test approach is modeled after the helm command tests.

This required some changes to the kubernetes client setup to make it
possible to use a fake. If we agree this pattern makes sense, it can be
applied to other commands.
