Adds awsPrefix config

[noslouch]

Most of the other S3 ember-cli-deploy plugins include a configuration to add prefix to files destined for an S3 bucket, e.g. to upload stuff to a nested path. This PR adds that config option, and a couple other items I noticed while digging around in the source.

• log output. I added some log output for verbose mode. I found this helpful while adding this feature
• _list regex. the regex in _list wasn't matching some revision keys due to including [^.]* in the pattern. ember-cli-deploy-revision-data uses version numbers and a commit hash by default in the form of #.#.#+<hash>, which means the literal . characters will fail the regex test. I changed the regex to match any character between archivePrefix and .zip. I think the fact that the pattern also includes .zip should ensure that it only matches zipped asset bundles.

Hi @noslouch and thanks for adding this 👍 . Looks great! Can you please add tests for the changes you made? Happy to merge this in with tests.

[noslouch]

can do!

hey @LevelbossMike! I added a couple assertions for uploading and activating. Let me know if that's ok, or if you'd also like to assert against revision fetching as well.

@noslouch This looks very nice 🎉 Yes please also add a test that listing works as expected when using a prefix.

All righty. I had to tweak the signature of setupTestData so the revision tests would have something to find on S3 when it looked for files under the awsPrefix. Let me know if there's anything else! @LevelbossMike
