remove auto provision, simplify js hs api

[autodidaddict]

This PR does a few main things:

• changes behavior so that host services resources (currently kv, objectStore) are never automatically provisioned
• JS API for host services has been changed as per Simplify and Improve Host Services Developer Experience #332
• Fixed a bug in host services calls that didn't return an error propagated from the service itself

@jordan-rash saw this yesterday, also on macos. Taking a look at this...

Update: opened #335 to address.

This PR looks great.

It would make a lot of sense to keep JIT provisioning support, but make it conditional by creating a jit_provisioning flag in the node host services config (defaulting to true).
