Pipeline Enhancement - Add workflow_dispatch inputs

[WadeBarnes]

Add workflow_dispatch inputs to allow for build/deploy to be performed manually.

The inputs should allow the user to specify all of the build parameters; git repositories, git refs, base images, etc. Logical defaults should be provided for all parameters so the user only has to update what's needed for the build they are triggering.

The resulting images and deployments should accurately reflect the specified inputs.
