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:
