Nomad 0.9 incidentally set effective capabilities that is higher than
what's expected of a `nobody` process, and what's set in 0.8.
This change restores the capabilities to ones used in Nomad 0.9.

plugins/driver: update driver interface to support streaming stats
client/tr: use streaming stats api
TODO:
* how to handle errors and closed channel during stats streaming
* prevent tight loop if Stats(ctx) returns an error
drivers: update drivers TaskStats RPC to handle streaming results
executor: better error handling in stats rpc
docker: better control and error handling of stats rpc
driver: allow stats to return a recoverable error
This PR fixes various instances of plugins being launched without using
the parent loggers. This meant that logs would not all go to the same
output, break formatting etc.
Re-export the ResourceUsage structs in drivers package to avoid drivers
directly depending on the internal client/structs package directly.
I attempted moving the structs to drivers, but that caused some import
cycles that was a bit hard to disentagle. Alternatively, I added an
alias here that's sufficient for our purposes of avoiding external
drivers depend on internal packages, while allowing us to restructure
packages in future without breaking source compatibility.
This implements the InternalPluginDriver interface in each driver, and
calls the cancellation fn for their respective eventers.
This fixes a per task goroutine leak during test suite execution.

Prior to 97f33bb1537d04905cb84199672bcdf46ebb4e65, executor cgroup validation errors were
silently ignored. Enforcing them reveals test cases that missed them.
This doesn't change customer facing contract, as resource struct is
is either configured or we default to 100 (much higher than 2).
