Is there a way to catch storage class access modes at deployment time?

[colearendt]

Otherwise we leave the user a long debugging trail figuring out that we require ReadWriteMany by default

It'd be nice if there was a reliable way to see storage classes available for users and optionally fail

[colearendt]

We should be able to do this with some complicated ranges and such after doing something like kubectl get storageclasses using the lookup function. Probably belongs as a rstudio-library helper that we use the permitted AccessModes and the named storage class with.

Also need a way to find the "default" storage class... either by "ranging" through all of them or finding a filter that we can pass...
