Mahmood Ali 7897dec9d9 api: move formatFloat function
`helpers.FormatFloat` function is only used in `api`.  Moving it and
marking it as private.  We can re-export it if we find value later.

Mahmood Ali b768b31e3e api: embed pointer conversion functions
Embed pointer conversion functions in the API package to avoid
unnecessary package dependency.  `helper` package imports more
dependencies relevant for internal use (e.g. `hcl`).

Mahmood Ali 6bdb9864de api: remove MockJob from exported functions
`api.MockJob` is a test utility, that's only used by `command/agent`
package.  This moves it to the package and removes it from the public
API.

Mahmood Ali 253532ec00 api: avoid import nomad/structs pkg
nomad/structs is an internal package and imports many libraries (e.g.
raft, codec) that are not relevant to api clients, and may cause
unnecessary dependency pain (e.g. `github.com/ugorji/go/codec`
version is very old now).

Here, we add a code generator that imports the relevant constants from
`nomad/structs`.

I considered using this approach for other structs, but didn't find a
quick viable way to reduce duplication.  `nomad/structs` use values as
struct fields (e.g. `string`), while `api` uses value pointer (e.g.
`*string`) instead.  Also, sometimes, `api` structs contain deprecated
fields or additional documentation, so simple copy-paste doesn't work.
For these reasons, I opt to keep the status quo.

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.

Related to https://github.com/hashicorp/nomad/issues/5165 .

Michael Schurter 8a6b1acaa6 drain: fix node drain monitoring
The whole approach to monitoring drains has ordering issues and lacks
state to output useful error messages.

AFAICT to get the tests passing reliably I needed to change the behavior
of monitoring.

Parts of these tests are skipped in CI, and they should be rewritten as
e2e tests.

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.

Mahmood Ali f72e599ee7 Populate alloc stats API with device stats
This change makes few compromises:

* Looks up the devices associated with tasks at look up time.  Given
that `nomad alloc status` is called rarely generally (compared to stats
telemetry and general job reporting), it seems fine.  However, the
lookup overhead grows bounded by number of `tasks x total-host-devices`,
which can be significant.

* `client.Client` performs the task devices->statistics lookup.  It
passes self to alloc/task runners so they can look up the device statistics
allocated to them.
  * Currently alloc/task runners are responsible for constructing the
entire RPC response for stats
  * The alternatives for making task runners device statistics aware
don't seem appealing (e.g. having task runners contain reference to hostStats)

* On the alloc aggregation resource usage, I did a naive merging of task device statistics.
  * Personally, I question the value of such aggregation, compared to
costs of struct duplication and bloating the response - but opted to be
consistent in the API.
  * With naive concatination, device instances from a single device group used by separate tasks in the alloc, would be aggregated in two separate device group statistics.

Michael Schurter 949938534b api: never return EOF from Logs error chan
Closing the frames chan is the only race-free way to signal to receivers
that all frames have been sent and no errors have occurred.

If EOF is sent on error chan receivers may not receive the last frame
(or frames since the chan is buffered) before receiving the error.

Closing frames is the idiomatic way of signaling there is no more data
to be read from a chan.

Update node-drain logging message to clearer for operators.
This change updates the console log message when performing a node
drain and particulary when a node has marked all allocs for
migration. Previously it logged 'drain complete' which was a little
confusing to operators as the node is not drained at this point.

Before the drain CLI would block until the node was marked as completing
drain operations. While technically correct, it could lead operators (or
more likely: scripts) to shutdown drained nodes before all of its
allocations had *actually* terminated.

This change makes the CLI block until all allocations have terminated
(unless ignoring system jobs).
