Mahmood Ali 8923ea4663 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.

Merge pull request #4845 from hashicorp/r-exec-refactor 
Update exec driver to match rawexec
 2018-11-12 20:59:32 -05:00
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.

Mahmood Ali 9a45837c4e 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.
