If there are more than 1 room with the same set of users, the import
will fail due to a unique constraint on the huddle_hash. Figuring out
why and which room is causing this database error is kinda difficult.
We deduplicate those cases here and simply merge the rooms together.
Note however, that the deduplication does not work as expected so we
simply ignore them all together for now and only raise an exception
along some logging output. At least this way, it is pretty clear what is
wrong and you do not have to wait to get a database error during the
actual import.
We also ignore empty huddle rooms since those are the duplicates that
caused problems for me and if they are empty, ignoring them is easier
than trying to get the merge to work.
Not sure where those channels come from since we discovered this with
production data.

This resolves the issues reported in #20108, major chunk of which were
due to the incomplete support for importing the livechat streams/messages
in the tool. So, it's best not to import any livechat streams/messages for
now until a complete support for importing the same is developed.
This commit adds functionality to import messages from the
Discussions having direct channels as their parent. As we don't
have topics in the PMs, the messages are imported in interleaved
form in the imported direct channels/PMs.
This was completely unsupported earlier and would have resulted in
an error.
While the STREAM_LINK_REGEX and STREAM_TOPIC_LINK_REGEX
identifies the stream and topic mentions in the content
correctly (tested by printing out the matches), the
stream/topic mentions are still not linked to the
corresponding streams/topics for imported messages, as
a `zulip_message` instance is required for linking these
mentions to actual streams/topics (see `StreamPattern`
class in `markdown/__init__.py`) which is not provided
while processing the markdown for imported messages.
This commit allows to import the following from rocketchat:
* All users
* All public/private channels
* All teams and its public/private channels
* All discussion rooms as topics in their parent channel
* All the messages in all the channels
* All private conversations
* Reactions on messages (except for custom emojis)
* Mentions in messages (except @all, @here mentions)
