[docker-fpm-frr]: Add unified-split mode to routing config (#11938)

Browse Source 
- Why I did it
The values for config_db "docker_routing_config_mode" are:

separated: FRR config generated from ConfigDB, each FRR daemon has its own config file
unified: FRR config generated from ConfigDB, single FRR config file
split: FRR config not generated from ConfigDB, each FRR daemon has its own config file
This commit adds:
split-unified: FRR config not generated from ConfigDB, single FRR config file

- How I did it
In docker_init.sh, when split-unified is used, the FRR configs are not generated
from ConfigDB. What's more, "service integrated-vtysh-config" is configured in vtysh.conf.

- How to verify it
FRR config not overwritten when FRR container starts.
