Lang Martin a4784ef258 csi add allocation context to fingerprinting results (#7133) 
* structs: CSIInfo include AllocID, CSIPlugins no Jobs

* state_store: eliminate plugin Jobs, delete an empty plugin

* nomad/structs/csi: detect empty plugins correctly

* client/allocrunner/taskrunner/plugin_supervisor_hook: option AllocID

* client/pluginmanager/csimanager/instance: allocID

* client/pluginmanager/csimanager/fingerprint: set AllocID

* client/node_updater: split controller and node plugins

* api/csi: remove Jobs

The CSI Plugin API will map plugins to allocations, which allows
plugins to be defined by jobs in many configurations. In particular,
multiple plugins can be defined in the same job, and multiple jobs can
be used to define a single plugin.

Because we now map the allocation context directly from the node, it's
no longer necessary to track the jobs associated with a plugin
directly.

* nomad/csi_endpoint_test: CreateTestPlugin & register via fingerprint

* client/dynamicplugins: lift AllocID into the struct from Options

* api/csi_test: remove Jobs test

* nomad/structs/csi: CSIPlugins has an array of allocs

* nomad/state/state_store: implement CSIPluginDenormalize

* nomad/state/state_store: CSIPluginDenormalize npe on missing alloc

* nomad/csi_endpoint_test: defer deleteNodes for clarity

* api/csi_test: disable this test awaiting mocks:

Lang Martin 88316208a0 csi: server-side plugin state tracking and api (#6966) 
* structs: CSIPlugin indexes jobs acting as plugins and node updates

* schema: csi_plugins table for CSIPlugin

* nomad: csi_endpoint use vol.Denormalize, plugin requests

* nomad: csi_volume_endpoint: rename to csi_endpoint

* agent: add CSI plugin endpoints

* state_store_test: use generated ids to avoid t.Parallel conflicts

* contributing: add note about registering new RPC structs

* command: agent http register plugin lists

* api: CSI plugin queries, ControllerHealthy -> ControllersHealthy

* state_store: copy on write for volumes and plugins

* structs: copy on write for volumes and plugins

* state_store: CSIVolumeByID returns an unhealthy volume, denormalize

* nomad: csi_endpoint use CSIVolumeDenormalizePlugins

* structs: remove struct errors for missing objects

* nomad: csi_endpoint return nil for missing objects, not errors

* api: return meta from Register to avoid EOF error

* state_store: CSIVolumeDenormalize keep allocs in their own maps

* state_store: CSIVolumeDeregister error on missing volume

* state_store: CSIVolumeRegister set indexes

* nomad: csi_endpoint use CSIVolumeDenormalizePlugins tests
