Implemented Azure e2e tests

Implement Azure template e2e tests. Closes #210.

Looking at the latest test failure, my suspicion is the names aren't unique for the cluster names for each provider test and they're running over each other. It might be worth appending a provider name to the end of the ManagedCluster that gets created for each test so they don't clobber each other and race.

@kylewuolle In the future can use try not to use force-pushes? At least not after someone has initially reviewed your code. It makes reviewing your code changes after a big initial review harder, you can always just squash the ending result into a single commit.

lgtm, but a couple of my prior comments are still unresolved, either unchanged or no comment was added to them.

The !found || err != nil logic here should be changed, perhaps this was missed in the last round of changes.

Not sure if getAzureInfo can be a GinkgoHelper as well, it doesn't look like it runs in an Eventually.

Using errors.Is is the better idea here because errors.Is supports wrapped errors while err == will not.

@kylewuolle please squash commits like "fix linting error" and let's verify azure part is green before we land it

@kylewuolle if you cannot reproduce the latest failure locally -- you can use try to use the tmate action: https://github.com/mxschmitt/action-tmate to live debug what's going on with the infrastructure-aws provider, it'll host a tmate session you can ssh into so you can get into the actions container and figure out potentially what's going on.

My best guess is something is going wacky with the credential creation part, as the CAPA provider won't start if the aws-variables secret can't be mounted, perhaps it's malformed or something.

We might want to modify the e2e test to run collectLogArtifacts during controller test failures as well. I intend to make this change in #360

As discussed, go ahead and merge what you currently have @kylewuolle and I'm going to work to get the E2E tests all green in #360
