executor: implement streaming stats API
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

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.

Mahmood Ali d23f47736c drivers/exec: run as `nobody` by default
libcontainer based drivers (e.g. exec, java) should default to running
processes as `nobody` [1]; but libcontainer treats empty user as `root`
in our case (either because of default or due to `root` being current
user).

Danielle Tomlinson 7b31027ea3 exec: Return undetected when not running as root
This is an unrecoverable error, so we should only do this check once,
rather than returning unhealthy constantly.

Plugin client's handle plugin dying

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.

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.

Namely, remove the `enabled` configuration flag, as it's specific to
`raw_exec` driver.  Also, pass resource limits to underlying call.
