feat: transient troubleshooting container

[DerekRoberts]

Create an image that can be deployed for troubleshooting. It should timeout, because leaving an overpowered tool active is a vector for attack.

Includes:

• git
• local write access, probably a volume
• options for languages (node, python, etc.)
• proper bash shell
• psql
• database tools i don't know/understand
• t.b.d
