SuvarnaMeenakshi abe7ef7e2e [baseimage]: support building multi-asic component (#3856)
- move single instance services into their own folder
- generate Systemd templates for any multi-instance service files in slave.mk
- detect single or multi-instance platform in systemd-sonic-generator based on asic.conf platform specific file.
- update container hostname after creation instead of during creation (docker_image_ctl)
- run Docker containers in a network namespace if specified
- add a service to create a simulated multi-ASIC topology on the virtual switch platform
