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.

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.

Nick Ethier bcc5c4a8bd clientv2: base driver plugin (#4671)
Driver plugin framework to facilitate development of driver plugins.

Implementing plugins only need to implement the DriverPlugin interface.
The framework proxies this interface to the go-plugin GRPC interface generated
from the driver.proto spec.

A testing harness is provided to allow implementing drivers to test the full
lifecycle of the driver plugin. An example use:

func TestMyDriver(t *testing.T) {
    harness := NewDriverHarness(t, &MyDiverPlugin{})
    // The harness implements the DriverPlugin interface and can be used as such
    taskHandle, err := harness.StartTask(...)
}
