[Infra] Remove container and host tsvb fields (#198134)

Closes #197993
## Summary

This PR removes the old tsvb fields used for containers before we
changed to the asset details view. They were used for displaying charts
but now we use lens formulas so those are no longer needed

## Testing

This PR removes old no longer used code so the testing should be for
regressions
- Go to Infrastructure Inventory
- Select Docker Container from the `Show` drop-down
- Click on any container:

- The asset details flyout and full page view should load as before (the
same as for hosts)
- Repeat same steps for host (and k8s pod)
