6b8c6836a9 Prioritize checking consumer context cancellation 
Tests expect that as soon as eventer shuts down immediately on context
cancellations; but golang does not guarantee priority when multiple
pending channels are ready in a select statement.

8ccb80bcea pull alpine image needed for test 
The test requires the image to be present locally, so importing it as
part of setup.

416b5240f4 Handle time.Duration in mock 
Mock driver config uses `time.Duration` fields but we initialize them
inconsistently, as time.Duration sometimes and as duration strings other
times.  Previously, `mapstructure` handles it and does the right thing.

This is no longer the case with MsgPack.  I could not find a good way to
bring back old behavior without too much complexity.  `MsgPack` extended
types weren't ideal here as we lose type information (e.g. int64 vs
string), and the input is a generic map and not a MsgPack serialization
of duration.

As such, I went with the simple solution of declaring the config field
as duration string, and panicing if the test doesn't pass a valid
string.

I found this to cause the smallest change in tests, but we can
alternatively force all to be int64 instead.

9d42f4d039 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.

1a17741e86 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

57f40c7e3e 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.

a5e1e4b59e Register exec driver plugin among some fixes 
Namely, remove the `enabled` configuration flag, as it's specific to
`raw_exec` driver.  Also, pass resource limits to underlying call.
