If the user wants to manage their user deployments in a separate helm release, they
still have to specify the user deployments in the umbrella dagster chart to generate
Although the workspace only needs the name/port of the deployment server, they'll still
have to specify the image and dagsterApiGrpcArgs for their user deployment since the
chart relies on the subchart schema for validation.
To improve ergonomics, we expose another field under dagit for them to specify the workspace.yaml
values without the unnecessary fields.
