Codecov Uploads prevent common error conditions

[trent-codecov]

With the multi step upload process, it is possible to upload things in the wrong order or omit a required step.

Goal:

Each step should perform the steps before it in the event that it is not completed.

• create report should check for commit and instead of failing, it would call create commit.
• create upload should check for report and commit and instead of failing, it would call create commit and/or report.

Considerations:

• Create commit and create report call celery tasks. Suggestion is to use celery task chaining to prevent ordering issues.
• Create commit and create report have different method signatures. The truly required info is present. However modifying the CLI to send the option info on create commit into the create report / create commit methods will allow this functionality to work better by default.
