HASURA: Allow specifying migrations/metadata from parent charts

[sbienkow-ninja]

Currently there's no way to depend on Hasura chart and mount migrations/metadata to it without vendoring it and placing appropiate folders inside chart directory. It'd be nice if it was possible to specify migrations/metadata folders from parent chart, for example by allowing parent to create required config maps (currently their names are hardcoded). I'm not aware of what a standard for doing so is, that's the first solution that came to my mind.

Hi, Sorry for the late reply. I was rather hoping this Helm missing feature to be implemented. It was supposed to be part of Helm v3.6.0, but has been postponed until further notice. I'd rather wait for this feature to be implemented. I still hope it will be part of v3.7 in September, but don't hesitate to contribute to this repo so it can be solved with the pattern you suggested (I couldn't think of a better approach anyway)
