[Enhancement] Allow to use telegram Bridge Bot multiple times

[sirdrakeistda]

In Matterbridge this is not a issue. I think the problem is that talk_matterbridge starts for every conversation a new matterbridge instance.

Problem

At the moment it is only possible to use a telegram Bridge bot for one single Group Bridge (e.g. group1_telegram <-> group1_nc) I can't use the same bot the same time for another group (e.g. group2_telegram <-> group2_nc). This is because talk_matterbridge creates second stream for fetching the messages from the telegram API. But there is only one stream allowed, so a Telegram Bridge Bot configured for two Groups will fail.

Solution:

talk_matterbridge should only start one single matterbridge instance. With this using the same bot a second time should work. Furthermore this consumes less resources.

This will need to be done in the spreed repo. Moving the issue.

This issue affects not only telegram bot. Also other connections/acounts (e.g. XMPP could) only be used for one single bridge at the same time.
