Ondrej Zajicek (work) 3b56bf8849 BFD: Better handling of BFD options in BGP configs
Merge multiple BFD option blocks in BGP configs instead of using the last
one. That is necessary for proper handling of templates when BFD options
are used both in a BGP template and in a BGP protocol derived from that
template.
