To enable cert management for all resources (#1027) , workers should have a volume in their baggageclaim when they are first registered which contains a set of certs to use for resources.

When a worker registers, a volume should be created in its baggageclaim. This volume should:

• Be created with a consistent name across all workers
• Always exist on a worker before we start using it (creating resource containers)

We can leave the population of the certs in that volume for later.
