Mahmood Ali 9909d98bee Track Basic Memory Usage as reported by cgroups 
Track current memory usage, `memory.usage_in_bytes`, in addition to
`memory.max_memory_usage_in_bytes` and friends.  This number is closer
what Docker reports.

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.

Alex Dadgar 1e3c3cb287 Deprecate IOPS 
IOPS have been modelled as a resource since Nomad 0.1 but has never
actually been detected and there is no plan in the short term to add
detection. This is because IOPS is a bit simplistic of a unit to define
the performance requirements from the underlying storage system. In its
current state it adds unnecessary confusion and can be removed without
impacting any users. This PR leaves IOPS defined at the jobspec parsing
level and in the api/ resources since these are the two public uses of
the field. These should be considered deprecated and only exist to allow
users to stop using them during the Nomad 0.9.x release. In the future,
there should be no expectation that the field will exist.

Danielle Tomlinson 393b76ed7f 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.

driver packages, and is useful for 3rd party plugins.

Mahmood Ali c5de71a424 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.

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(...)
}
