Implements #229: the action values in the request log now say what they mean, with no aliases.
too_large is now request_header_too_large.
rate_limited is now client_is_rate_limited.
rule_blocked is now blocked_by_block_rule.
denied is now client_denied.
banned splits into temporarily_banned and permanently_banned.
The ban value comes from the ban itself. banForAttack and banForCrowdSec now return the action for the ban they make.
What the diff does not show
A request that makes an attack ban permanent logs permanently_banned. So does a repeat attack that is banned permanently at once.
In observe mode, would_action names the ban enforce mode would have made. When no alert would be sent, the ban is not worked out in full, so the value comes from WouldBePermanent.
A request over a rate limit stays client_is_rate_limited, even when the ban it makes is permanent. The issue names one value for it.
Disclosures
The offence kind rule_blocked also changes, as the sww_offences_total label and the key in clients.json. sww discriminator stops at startup on a clients.json holding the old key, because parse in internal/state/state.go refuses unknown fields. The file's version stays 1, per the ruling for repos before 1.0.
country_denied and waf_blocked are unchanged. #192 renames waf_blocked.

- `too_large` is now `request_header_too_large`.
- `rate_limited` is now `client_is_rate_limited`.
- `rule_blocked` is now `blocked_by_block_rule`.
- `denied` is now `client_denied`.
- `banned` splits into `temporarily_banned` and `permanently_banned`.
The ban value comes from the ban itself. `banForAttack` and `banForCrowdSec` now return the action for the ban they make.
**What the diff does not show**
- A request that makes an attack ban permanent logs `permanently_banned`. So does a repeat attack that is banned permanently at once.
- In `observe` mode, `would_action` names the ban `enforce` mode would have made. When no alert would be sent, the ban is not worked out in full, so the value comes from `WouldBePermanent`.
- A request over a rate limit stays `client_is_rate_limited`, even when the ban it makes is permanent. The issue names one value for it.

internal/discriminator/bans.go, banForLimit: nothing reads the value it now returns. rateLimits.check discards it, and byteLimits.check and refusalLimit.check put it in a verdict whose action is not used, as the comment on afterAnswer in heuristics.go says. A reader is told a byte limit ban gets a ban action, when that request's action does not change. Acceptable: banForLimit returns nothing, as on next, with no WouldBePermanent call of its own and no "returns the action" sentence; the verdicts in bytelimits.go and refusallimit.go carry only figures.
internal/discriminator/observe_test.go, TestBanActionSaysWhetherTheBanRunsOut: it sets no alert destination, so it never reaches the banForAttack return used when an alert would be sent, and no other test checks would_action there for a permanent ban. Acceptable: a case in observe mode with an alert destination set, for a repeat attack that would be banned permanently, asserting would_action is permanently_banned.
PR body, "An existing clients.json loses its count under the old key.": false. parse in internal/state/state.go refuses unknown fields, so sww discriminator stops at startup on a clients.json holding rule_blocked, which every client with an offence has. Acceptable: correct that sentence. The code stays as it is: state files change in place, per #192 (comment).
docs/request-log.md, "permanently_banned: refused under a ban that never runs out, or for a request that made such a ban or made its client's ban permanent;": fails on first reading, because the request is what was refused, not why. Acceptable: "permanently_banned: refused under a ban that never runs out, including a ban this request made or made permanent;".
Judgement call: a request over a rate limit stays client_is_rate_limited even when its ban is permanent, since #229 names one value for it; not a finding.

Ledger.active and activeBan in internal/bans/bans.go, read by active_ban in internal/discriminator/bans.go: a client covered by both a temporary ban and a permanent ban can be logged temporarily_banned. active returns the first active ban it finds across netblock lengths, and activeBan the newest within a netblock. Neither looks for a permanent ban. It happens with a temporary ban on the client's /32 and a permanent admin ban on its /24, and with a newer temporary admin ban over an older permanent ban on one netblock. The line gives a ban_expires time after which the client is still refused. This misses "by whether the ban covering the client runs out" in #229, and makes the new SPEC.md sentence "Under a permanent ban the action is permanently_banned." false. Acceptable: when any active ban covering the client is permanent, Check and Find return a permanent one, so action is permanently_banned and ban_expires is permanent. Update the comment on activeBan, and add a test for each of the two cases.

Rename too_large, rate_limited, rule_blocked and denied, and split banned
into temporarily_banned and permanently_banned by whether the ban runs out.
A client under both a temporary and a permanent ban gets the permanent one.
A request that makes a ban permanent gets permanently_banned. A ban rule, a
trap path or a CrowdSec decision gets the value for the ban it makes, and in
observe mode would_action names the ban enforce mode would have made.
The offence kind rule_blocked follows, as a metric label and a key in
clients.json.
