Slavi Pantaleev 77b919aec6 Become compatible with official matrix-appservice-irc Docker image
This change allows us to work with both our existing Docker image
(`tedomum/matrix-appservice-irc:latest`) and with the
official Docker image (`matrixdotorg/matrix-appservice-irc`).

The actual change to the official Docker image requires more testing
and will be done separately.

# Ideally, we'd like to generate the final registration.yaml file by ourselves.
#
# However, the IRC bridge supports multiple servers, which leads to multiple
# users/aliases/rooms rules in the registration file.
#
# Generating a proper file by ourselves is complicated and may lead to deviation
# from what the bridge is doing.
#
# Instead, we do another hacky thing - asking the bridge to generate a template,
# and then we parse it and fix it up with our own AS/HS token.
# We need to do this, because:
# - we'd like to have an up-to-date registration file
# - we can achieve this by asking the bridge to rebuild it each time
# - however, the bridge insists on regenerating all tokens each time
# - .. which is not friendly for integrating with the homeserver
#
# So we have a hybrid approach. We ask the bridge to always generate
# an up-to-date file, and we fix it up with some static values later on,
# to produce a final registration.yaml file, as we desire.
