Authenticate CrowdStrike client

[aiwilliams]

This establishes a connection to the CrowdStrike API using OAuth2. There is no publicly available Node client that I could find documented or listed in their open source projects.

I'd like to think we could create a generic client for use in integrations that don't have their own; consider this another contribution to the set of examples when the time comes to make that happen 😄

Note that this is the third project to use Polly. I think we need to pull up the code into a library, and also fix the DefinitelyTyped Polly modules (submit PRs).

@erkangz Please review the set of entities/relationships we're going for, to be sure they're the ones you'd expect and the names are good. Thanks!

Entity types and relationships look great. Mapped relationships to Host/Device entities will come later, right?
