`disable = false` is a double negative, and a bool named disable cannot
express opt-in anyway: it zero-values to false, so the flag was inert and
opt-in rested entirely on the device list being empty.
`enable` defaults to false and is now the real gate -- Initialize, Metrics
and DebugInput all return early unless it is set. The two existing guards
remain: an empty device list is still a no-op, and no default URL is ever
synthesized.
Configuring devices while enable is false is always a mistake, so that
combination logs one error instead of silently collecting nothing.
Adds binding tests for the flag across toml, json, yaml and UP_UNAS_ENABLE
(the env name derives from the xml tag, not the json one), plus a test that
all three shipped examples default to off. Both were verified by mutation:
breaking a struct tag or flipping an example fails the suite.

Adds a new `unas` input plugin that polls UNAS Pro storage consoles and
exports console health, storage pools, disks and shares to Prometheus,
InfluxDB and DataDog.
UNAS is a separate plugin rather than a device type inside inputunifi
because a storage-only console has no Network application: it cannot
answer /status, has no sites, and shares none of the UniFi device schema.
The plugin is opt-in and inert until an operator names a console. Opt-in
is expressed as "no devices configured" rather than a `disable` flag,
because a bool named `disable` zero-values to false and so cannot make a
plugin default-off. Initialize returns silently on an empty device list
and, unlike inputunifi, nothing synthesizes a default URL.
Two behaviours are worth calling out for reviewers:
- Metrics returns (metrics, nil) whenever any console was collected.
poller.collectMetrics uses `if err != nil {} else if metric != nil`,
so returning both would discard every healthy console because one
failed. Only a total failure returns an error.
- Re-auth fires on total failure, not on a 401. A mid-session 401 from
GetData surfaces as ErrInvalidStatusCode, not ErrAuthenticationFailed,
so there is no sentinel to match on. Session expiry fails all four
endpoints at once, which is exactly the total-failure case.
Prometheus metrics use the `unifi_unas_` prefix, which diverges from the
`unas_` prefix used by the reference implementation; dashboards built
against that will need query edits.
Requires unifi/v5 v5.31.0 for the UNAS client and structs.
Credit to alexgreenbank/unaspoller for mapping the endpoints.

Decouples Prometheus scrape cadence from upstream UniFi API calls so a
429 backoff loop on the controller side no longer stalls /metrics. The
output plugin now owns a 60s background poller (configurable) whose
result is served from an in-memory cache. Concurrent /scrape requests
for the same target are coalesced via singleflight to prevent a noisy
scraper from multiplying upstream load.
Adds two new metrics so operators can detect cache staleness and
refresh failures independently:
- unpoller_prometheus_cache_age_seconds
- unpoller_prometheus_refresh_failures_total
Background goroutine recovers from panics so a malformed input payload
no longer silently kills refreshes.

Closes#1001. Mirrors the DataDog plugin's global tags feature for
InfluxDB. Per-metric tags take precedence on key collision so
site/device identifiers can never be overwritten by a misconfigured
global. Configurable via TOML/JSON/YAML under influxdb.tags.

Adds log_unknown_types config option (default: false) to control logging
of unknown UniFi device types. When disabled (default), unknown devices
are silently ignored to reduce log volume. When enabled, they are logged
as DEBUG messages instead of ERROR. Addresses issue #912.
