[pmg-devel] [PATCH pmg-api/pmg-gui v3] allow / in local part of pmg-email-address

[Stoiko Ivanov <s.ivanov@proxmox.com>]

v2->v3:
* addressed Thomas' feedback (huge thx!!)
* changed the API to have a dedicated /statistics/detail call, which handles
  all 3 detail-statistics calls (based on the required type parameter)
* dropped the already applied patches

cover-letter for previous series:
v1->v2:
* Had a chat with Thomas off-list - who (righfully) pointed out that the paths
'contact' and 'contacts' seem a bit shoddy and counterintuitive
* reimplemented the change so that it still uses '/contact' as prefix,
but instead of providing the address as next component uses 'detail' (and
provides the address in the detailaddress parameter)
(the two points above apply to 'sender' and 'receiver' as well)

* individual notes below the individual patches (where applicable)

original cover-letter:
The following patchset is a result of investigating a thread in our
community forum [0].

While I'd consider e-mail addresses with '/' in the local-part quite odd,
as so often smtp RFCs are quite liberal with what smtp servers (have to)
accept. Postfix happily accepts mails with '/' in the local-part, and
should they end up in the quarantine, it is currently not possible to
remove them (short of waiting for quarantine retention period).

the 4 places where we use the pmg-email-address format are:
* quarantine (pmail parameter)
* statistics (contact, receiver, sender detail views)
* fetchmail
* pbsconfig (username)

the first two are problematic in the sense that external sources might
cause a mail-address with '/' to get stored. pbsconfig stores a username
with '/' (which then fails since the repository verification does not
expect a '/' in the username/token), fetchmail accepts it (and stores its
config with all special characters escaped)
only the statistics api calls are problematic, since the detail views pass
the mail-address as path component (and the decoding inside pve-http-server
breaks the api call resolution) - addressing this is the main part of the
patchset.

It follows a similar series by Dominik for the user blocklists [1].

patch 1/5 for the api is a cleanup that caught my eye
patches 2+3 for the api could probably be squashed (happy to send a v2 for
this - but feel free to squash them if this gets applied as is)

tested it a bit on my setup (with a limited set of addresses in the
statistics database).
