1791: Enhanced session handling r=mergify[bot] a=ghostwheel42
## What type of PR?
bug-fix
## What does this PR do?
- replaces flask_kvsession and simplekv with a mailu-specific session store
- call cleanup_sessions before first request and not on startup.
this allows to run cmdline actions without redis (and makes it faster)
- allow running without redis for debugging purposes by setting MEMORY_SESSIONS to True
- don't sign session id, as it has plenty of entropy (as suggested by nextgens)
- adds method to prune a user's sessions

1754: centralize Webmail authentication behind the admin panel (SSO) r=mergify[bot] a=nextgens
## What type of PR?
Enhancement: it centralizes the authentication of webmails to the admin interface.
## What does this PR do?
It implements the glue required for webmails to do SSO using the admin interface.
One of the main advantages of centralizing things this way is that it reduces significantly the attack surface available to an unauthenticated attacker (no webmail access until there is a valid Flask session).
Others include the ability to implement 2FA down the line and rate-limit things as required.

1758: Implement a simpler credential cache (alternative to #1755) r=mergify[bot] a=nextgens
## What type of PR?
Feature: it implements a credential cache to speedup authentication requests.
## What does this PR do?
Credentials are stored in cold-storage using a slow, salted/iterated hash function to prevent offline bruteforce attacks. This creates a performance bottleneck for no valid reason (see the
rationale/long version on https://github.com/Mailu/Mailu/issues/1194#issuecomment-762115549).
The new credential cache makes things fast again.
This is the simpler version of #1755 (with no new dependencies)

1776: optimize generation of transport nexthop r=mergify[bot] a=ghostwheel42
## What type of PR?
bug-fix and enhancement.
## What does this PR do?
Possibly there should be more input validation when editing a relay, but for now this tries to make the best out of the existing "smtp" attribute while maintaining backwards compatibility. When relay is empty, the transport's nexthop is the MX of the relayed domain to fix#1588
```
RELAY NEXTHOP TRANSPORT
empty use MX of relay domain smtp:domain
:port use MX of relay domain and use port smtp:domain:port
target resolve A/AAAA of target smtp:[target]
target:port resolve A/AAAA of target and use port smtp:[target]:port
mx:target resolve MX of target smtp:target
mx:target:port resolve MX of target and use port smtp:target:port
lmtp:target resolve A/AAAA of target lmtp:target
lmtp:target:port resolve A/AAAA of target and use port lmtp:target:port
target can also be an IPv4 or IPv6 address (an IPv6 address must be enclosed in []: [2001:DB8::]).
```
When there is proper input validation and existing database entries are migrated this function can be made much shorter again.

- the session key is now generated using
- a hash of the uid seeded by the apps secret_key (size: SESSION_KEY_BITS)
- a random token (size: 128 bits)
- the session's creation time (size: 32 bits)
- redis server side sessions are now refreshed after 1/2 the session lifetime
even if not modified
- the cookie is also updated if necessary
This can be used to delete all sessions belonging to a user/login.
For no it just iterates over all sessions.
This could be enhanced by using a prefix for and deleting by prefix.
- call cleanup_sessions on first kvstore access
this allows to run cmdline actions without redis (and makes it faster)
- Allow development using DictStore by setting REDIS_ADDRESS to the empty string in env
- don't sign 64bit random session id as suggested by nextgens

1783: Switch to server-side sessions r=mergify[bot] a=nextgens
## What type of PR?
bug-fix
## What does this PR do?
It simplifies session management.
- it ensures that sessions will eventually expire (*)
- it implements some mitigation against session-fixation attacks
- it switches from client-side to server-side sessions (in Redis)
It doesn't prevent us from (re)-implementing a "remember_me" type of feature if that's considered useful by some.

1610: add option to enforce inbound starttls r=mergify[bot] a=lub
## What type of PR?
Feature
## What does this PR do?
It implements a check in the auth_http handler to check for Auth-SSL == on and otherwise returns a 530 starttls error.
If INBOUND_TLS_ENFORCE is not set the behaviour is still the same as before, so existing installations should be unaffected.
Although there is a small difference to e.g. smtpd_tls_security_level of Postfix.
Postfix already throws a 530 after mail from, but this solution only throws it after rcpt to. auth_http is only the request after rcpt to, so it's not possible to do it earlier.
### Related issue(s)
#1328 is kinda related, although this PR doesn't solve the issue that the headers will still display ESMTP instead of ESMTPS
