Previously, the crawler pods use preferred node affinity, instead of
required node affinity. This results in crawler nodes running on the
main node pool. Instead, we want to ensure crawler nodes are running on
dedicated node pool (if configured).
- Converts 'preferred node affinity' to 'required node affinity' for
the node pool, while keeping preferred pod affinity for keeping all
crawler / redis pods together.
- For profiles, updates to same node affinity, and also adds
resource constraint to match a single crawler for profile browser,
which did not have resource constraints.
Instead of adding the app templates launched from the backend via
`backend/btrixcloud/templates`, add them to a configmap and mount the
configmap in the same location.
This allows these templates to be updated, like other values in
charts/... without having to rebuild any of the images, speeding up dev
and maintenance time.
Changes include:
- move backend/btrixcloud/templates -> chart/app-templates/
- add app-templates/*.yaml to app-templates configmap
- mount app-templates configmap to /app/btrixcloud/templates/ in api and op containers
