Detection of the full set of plugin capabilities was added in Nomad
1.1 for the volume creation workflow, but these were not added to the
API response for plugins.
When a cluster doesn't have a leader, the `nomad operator debug`
command can safely use stale queries to gracefully degrade the
consistency of almost all its queries. The query parameter for these
API calls was not being set by the command.
Some `api` package queries do not include `QueryOptions` because
they target a specific agent, but they can potentially be forwarded to
other agents. If there is no leader, these forwarded queries will
fail. Provide methods to call these APIs with `QueryOptions`.
Enhance the CLI in order to return the host network in two flavors
(default, verbose) of the `node status` command.

The ?resources=true query parameter includes resources in the object
stub listings. Specifically:
- For `/v1/nodes?resources=true` both the `NodeResources` and
`ReservedResources` field are included.
- For `/v1/allocations?resources=true` the `AllocatedResources` field is
included.
The ?task_states=false query parameter removes TaskStates from
/v1/allocations responses. (By default TaskStates are included.)

The API decodeBody function will now check the content length
before attempting to decode. If the length is zero, and the out
interface is nil then it is safe to assume the API call is not
returning any data to the user. This allows us to better handle
passing nil to API calls in a single place.
Given that the values will rarely change, specially considering that any
changes would be backward incompatible change. As such, it's simpler to
keep syncing manually in the rare occasion and avoid the syncing code
overhead.
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.
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.
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.
Closes#4183
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).
