113205318c plugins: Add support for serving driver plugins 2018-12-01 17:30:54 +01:00

1c98fdf935 plugins: Move driver testing support to subpackage 
this allows us to drop a cyclical import, but is subobptimal as it
requires BaseDriver tests to move. This falls firmly into the realm of
being a hack. Alternatives welcome.

6756ffd052 drivers: Move client/drivers/env to drivers/shared/env 
As part of deprecating legacy drivers, we're moving the env package to a
new drivers/shared tree, as it is used by the modern docker and rkt
driver packages, and is useful for 3rd party plugins.

429c5bb885 Device hook and devices affect computed node class 
This PR introduces a device hook that retrieves the device mount
information for an allocation. It also updates the computed node class
computation to take into account devices.

TODO Fix the task runner unit test. The environment variable is being
lost even though it is being properly set in the prestart hook.

dd47c590f0 Allow nullable fields in StatValues 
In state values, we need to be able to distinguish between zero values
(e.g. `false`) and unset values (e.g. `nil`).

We can alternatively use protobuf `oneOf` and nested map to ensure
consistency of fields that are set together, but the golang
representation does not represent that well and introducing a mismatch
between representations.  Thus, I opted not to use it.

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.

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.
