###############################################################################
## Wrapper for starting make inside sonic-slave container
#
#  Supported parameters:
#
#  * PLATFORM: Specific platform we wish to build images for.
#  * BUILD_NUMBER: Desired version-number to pass to the building-system.
#  * ENABLE_DHCP_GRAPH_SERVICE: Enables get-graph service to fetch minigraph files
#    through http.
#  * SHUTDOWN_BGP_ON_START: Sets admin-down state for all bgp peerings after restart.
#  * SONIC_ENABLE_SYNCD_RPC: Enables rpc-based syncd builds.
#  * USERNAME: Desired username -- default at rules/config
#  * PASSWORD: Desired password -- default at rules/config
#  * KEEP_SLAVE_ON: Keeps slave container up after building-process concludes.
#  * SOURCE_FOLDER: host path to be mount as /var/src, only effective when KEEP_SLAVE_ON=yes
