UI: Showed host reservations and allocation utilization by task on existing stats charts

In addition to this computation being wasteful, it introduces a bug
where the allocation on a stats tracker can update twice in one render,
which isn't allowed in Glimmer (ironically, Glimmmer's lack of
auto-memoization introduced the issue).

 - Sorting must be done on copies to preserve orders.
 - Indices should be reversed since rendering is also reversed (the back
   layer (the tallest) is rendered first to create the stacking effect).

This leverages the existing pre-processing being done in the
allocation-stats-tracker to also create additive percentages relative to
the allocation resources vs. the task resources.

This can then be used in a chart to create a stacked area representation
of consumption.

This binds a function to a target before passing it along to another
component. It's normal to expect to get to use `this` within functions
on components and controllers, but (sans actions) that doesn't happen
automatically.

Currently, PrimaryMetric is already overloaded on multiple dimensions:
metric and resource type.

This refactor will use multiple components as a form of control flow
instead spidering conditionals, which are only getting worse as the
charts for each resource type diverge.

Add a `PerAlloc` field to volume requests that directs the scheduler to test
feasibility for volumes with a source ID that includes the allocation index
suffix (ex. `[0]`), rather than the exact source ID.

Read the `PerAlloc` field when making the volume claim at the client to
determine if the allocation index suffix (ex. `[0]`) should be added to the
volume source ID.

Callers of `CSIVolumeByID` are generally assuming they should receive a single
volume. This potentially results in feasibility checking being performed
against the wrong volume if a volume's ID is a prefix substring of other
volume (for example: "test" and "testing").

Removing the incorrect prefix matching from `CSIVolumeByID` breaks prefix
matching in the command line client. Add the required elements for prefix
matching to the commands and API.

Create a convenience command for generating example CSI volume specifications,
similar to the existing `nomad job init` or `nomad quota init` commands.
