Release 0.17.0

[fajpunk]

This contains an alternate GitHub-path-based template rendering endpoint so we can further restrict the parts of Times Square that we expose to non-admins. Including this, there are three changes to enable us to implement these restrictions:

• This change (times-square)
• This RSP Jupyter extensions change, which uses the new endpoint (rsp-jupyter-extensions)
• This change to the GafaelfawrIngress, which restricts non-admins to only the new route

Here are all of the combinations, a checked box means it works:

• g_admin: times-square + rsp-jupyter-extensions + ingress
• g_admin: times-square + rsp-jupyter-extensions
• g_admin: times-square + ingress
• g_admin: times-square
• g_user: times-square + rsp-jupyter-extensions + ingress
• g_user: times-square + rsp-jupyter-extensions
• g_user: times-square + ingress
• g_user: times-square

This Times Square change works with every other change for both admin and non-admin users except for non-admin users using a lab without an updated rsp-jupyter-extensions. So:

• Times Square is safe to release with this change at any time
• rsp-jupyter-extensions is safe to release after this Times Square change is deployed everywhere
• The ingress changes will have to involve some more coordination
