Name log fields, metrics and the Core Rule Set package for what they are (closes #192)
Log field, metric, action and event names now say what they count
and, for timings, the unit. Package internal/waf is internal/coreruleset.

package discriminator
// The heuristic byte_limits. It reads SWW_BYTES_COUNT, and the byte limits
// and biased thresholds through the limiter and limitPercentages.
import (
"context"
"time"
)
// byteLimits counts the request's bytes, as countedBytes gives them, for the
// byte limits, once its report has come, and notes the client's byte totals for
// the log line; its requests stay there as the rate limits counted them. Only
// an allowed request has them counted, and only one the rate limits counted; in
// observe mode, not one that enforce mode would have refused. Bytes that take
// the client over a byte limit, as its limit percentage for the byte limits
// lowers it, break it, which bans the client; the response was passed on whole.
// Its figures are the window, the count and the limit.
