[Epic] Automatic blob storage access from notebook servers

[brendangadd]

As a user, I want easy access to all of my personal blob storage options directly from my notebook server without doing any special configuration.

• I want to work with blob storage similarly to how I work with other types of storage.
• I want to share storage with other project members; I don't want to give them access to my personal resources to do so.
• I want easy access to the data from different notebook servers.
• I want easy access to the data from different software within notebook servers.

Tasks

• Auto-mount MinIO storage in file system (e.g. fuse) of all notebooks, avoiding privilege escalation (Volume mount user s3 buckets (and others) on notebook creation #193)
• Auto-inject MinIO credentials into container via vault (Switch Vault injector for MinIO credentials to automatic #86)
• Auto-refresh MinIO credentials (fuse) ( Auto-refresh MinIO credentials in notebooks (fuse) #213)
• Auto-refresh MinIO credentials (/vault-injected) (Auto-refresh MinIO credentials in notebooks (/vault) #195)
• Remove credential-injection from notebook server "Configurations" (Remove credential-injection from notebook server "Configurations" #196)
• Update documentation to reflect above changes (Add info re. auto-mounted object storage to docs #231)

Fuse injection completed with https://github.com/StatCan/boathouse

I took the Pachyderm MinIO tenant removal out of scope of this epic as that tenant is not being auto-mounted into notebook servers. We can do that cleanup using other issues.

This is pretty much done isn't it? Or maybe continue it for Boathouse DataLake business

@blairdrummond Yep, let's consider this done and do enhancements post-epic. These features so far are epic enough on their own. :P
