Move ReadConfigFileOnSighup to gobgpd main

Reloading the config file on SIGHUP is behavior specific to gobgpd.
Attempts to expose it through the config API was awkward and could
make the api more confusing to use. This change moves that
functionality up into the gobgpd main and out of the library.
