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

Alex Dadgar 14ed757a56 Plugins use parent loggers 
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.

Mahmood Ali 64f80343fc drivers: re-export ResourceUsage structs 
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.

Danielle Tomlinson a9b9ad34dc drivers: Implement InternalPluginDriver interface 
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.

Alex Dadgar 693f244cce Plugin client's handle plugin dying 
This PR plumbs the plugins done ctx through the base and driver plugin
clients (device already had it). Further, it adds generic handling of
gRPC stream errors.

Danielle Tomlinson 880e5015f2 rawexec: Only use cgroups when running as root. 
If Nomad is not running as root, we should not try to use cgroups for pid
freezing.

This originally was implemented pre-driver-support in
https://github.com/hashicorp/nomad/blob/v0.8.6/client/driver/raw_exec.go#L120-L130

Alex Dadgar 204ca8230c Device manager 
Introduce a device manager that manages the lifecycle of device plugins
on the client. It fingerprints, collects stats, and forwards Reserve
requests to the correct plugin. The manager, also handles device plugins
failing and validates their output.
