Add functionality to remove bucket

[redroot]

References this issue: #9

Adds the command serverless client remove which empties the bucket and removes it. Some notes:

1. I refactored to make use of the functions that finds and empties the bucket from the deploy command. Im not overly familiar with the Class-style syntax in JS these days, so let me know what you think
2. I also added an arbitary 3 second delay to the remove process, as its clearly a very destructive process! Not sure if thats overkill though, thoughts?

@redroot This works cleanly. I'm going to look at the other PRs that are currently pending but this will get into a new version for sure.

@redroot Thanks for the PR! All merged. I will be updating the package over the weekend. If you don't see it before Monday please bug me about it. I still have to get some CI/CD setup on this so it isn't automatic yet.
