Add waiters for ElasticBeanstalk

[caldwecr]

When triggering operations that will run long (on the order of > 5 minutes and less than 24 hours) it would be useful to have predefined waiters available.

Presently I am looking for such support for update_environment operations.

We're happy to take a PR for this, and will also consider as a feature request.

Added to feature request backlog.

Reopening - deprecating usage of Feature Requests backlog markdown file.

I'm sorry this feature request took too long. I reached out to the elastic beanstalk team but didn't really get traction, so I went and implemented these myself. I tested the correctness of them by creating, updating, and terminating an environment.

I'll push these changes upstream and they'll be deployed in their next release.

I've changed delay to 20 seconds because of how long it takes to create/delete environments in most cases.
