Merge #1987
1987: Enhancement to the rate limits r=mergify[bot] a=nextgens

## What type of PR?

enhancement

## What does this PR do?

Turn the rate-limiters into something useful (that won't fire for no reason).

- fix rate-limiting on /webdav/
- it changes the rate-limiting behaviour from limiting a single IP address to a subnet of a reasonable size (/24 on v4 and /56 on v6 both are now configurable) : AUTH_RATELIMIT_IP / AUTH_RATELIMIT_IP_V4_MASK / AUTH_RATELIMIT_IP_V6_MASK
- It ensures we only use IP-based rate-limits for attempts on accounts that do not exist
- it creates a new rate limit preventing attackers from targetting a specific user account (separate from what's above) : AUTH_RATELIMIT_USER
- it introduces a rate limiting exemption mechanism whereby, upon authentication, users will see their source-ip address being exempt for a specific amount of time AUTH_RATELIMIT_EXEMPTION_LENGTH. A similar mechanism is available for web-based sessions (see below)
- It introduces in AUTH_RATELIMIT_EXEMPTION a comma separated list of network CIDRs that will be exempt from both types of rate limiting
- it implements device-tokens, as described on https://owasp.org/www-community/Slow_Down_Online_Guessing_Attacks_with_Device_Cookies to ensure that genuine users aren't locked-out by a malicious attacker abusing the rate-limit feature.

Things that could be improved include:
- the IP-based rate limiter flags attempts against "non-existing" accounts: it could go further and flag the number of unique non-existing accounts attempted (to prevent the case of a user making a typo in his MUA configuration)
- the IP address exemption mechanism doesn't pin the exemption to a specific username: any real user can trivially bypass the rate limits (and attempt to brute-force someone else's account)
