[pmg-devel] [PATCH pmg-api/gui] add quarantine self service button

[Dominik Csapak <d.csapak@proxmox.com>]

adds an option/api call to request an quarantine link for an
email whose domain is in the relay domains

for now, we do not expose that option to the ui, but this can easily be
added if wanted

NOTES on security:

this adds a world reachable api call, that can potentially send e-mails
to users that belong to a relay domain

this is ok, since anybody can already send e-mails to the users
via normal smtp, and since the content of the e-mail cannot be
controlled, the only thing a potential attacker can do is a dos attack
(which can always be done via resource exhaustion, e.g. send a lot of mail)

we could add more checks to make it more secure, but not so convenient:
* add an option for a admin-settable shared secret that users must enter
  (makes it harder for the user to self-service, since the user has to
  know the secret)
* only allow it from 'trusted networks' (this makes probably no sense)
* add an option to allow it from a specific subnet (similar to above,
  but seperate from mail flow, which could make sense, but is also
  not as convenient)

for now all text is hardcoded, templates could be used later on
(if users want that)

also i am open for alternate wordings for all texts, i basically chose
what came to mind first...

changes from v1:
* move config to 'spamquar' section
* show button also on admin interface
