Introduce support for multiple scanners

Dan Luhring requested to merge danluhring/container-scanning:support-multiple-scanners into master

Introducing this MR in response to this comment.

In preparation for adding more scanner choices beyond Trivy, this MR introduces a mechanism for callers of gtcs to select the scanner via a CLI switch:

gtcs scan <some-image>
# the existing output!

gtcs scan <some-image> --scanner trivy
# the existing output!

gtcs scan <some-image> --scanner grype
[ERROR] [2021-04-28 16:56:42 -0400] []  ▶  Unrecognized scanner selected: grype

In the code, the scanner is chosen using the function get_scan_function in lib/gcs/cli.rb, where a concrete scanner implementation (such as the class Gcs.Trivy) can be used behind the generalized abstraction of a "scan function".
