Custom Output Name in CircleCI

Allow for the definition of a custom output name for the compressed file artifact. Allow for variables to used in that name as well.

To explain, the goal of the process is to eventually have all successful builds on the master branch upload automatically to a github release AND a cloud storage folder. For the last to happen the filename would need to be unique. While the workaround to put each file in a uniquely named folder would work it just creates another level of file nesting that is unneeded.

Inspect the CircleCI orb's artifact compression and upload entry points; no specific file or test is named in the issue. Trace how the current compressed artifact name is produced, then verify that a configurable name supports variables and remains suitable for GitHub releases and cloud storage.
