Expand response of Status Badges to include optional information

[jrtitko]

Description

For badges, allow for the optional return of additional values such as the latest build number, the date last attempted built, the date last success/failure, etc. The optional values would return as part of the svg itself so that there would be a consistent presentation of the information.

Value

The optional additional information, such as build number, last successful date built, etc, would allow for a more comprehensive status page. The issue that brought this up is not knowing when the last time something successfully built when there is a current error showing. I've found repos that have been failing on automatic builds that we had no insight into because we didn't have the information in a centralized condensed location.

Definition of Done

Have a status badge returned that optionally includes additional information about the builds.
Additional fields could include but not be limited to:

• Date last successful build
• Date last failed build
• Vela build_number
• Build_commit

Effort (Optional)

This should be relatively easy as the information is already displayed in the Vela system. A few optional parameters for the desired information would have to be passed in and the returning SVG expanded to contain the results. Probably take a day or two.

Impacted Personas (Optional)

Users of Vela that have centralized status pages would be the primary beneficiary of this change.
