Artem Tiumentcev 76cd701382 Add fixed network mode for environments
Introduce a fixed network mode for environments. Specifically,
when this mode is activated, in the environment creation dialog
user is no longer prompted for a network and instead a network
previously assigned to the current project is used.

Network is assigned to project using project metadata key (custom)
with network ID as the value.
Specify this metadata key in Horizon config to be able to use it

This behavior is disabled by default and could be enabled by adding:

USE_FIXED_NETWORK = yes
FIXED_MURANO_NETWORK = murano_network

to the Horizon configuration.
