fixed (again) bitwise operation (or instead of and) in generate_lsp_obj
added (dirty) hack for old drafts (it seems that juniper supports -00 or -01
and i dont have anything else to play with)
right now LSPrep and LSPupd seems to work (at least juniper doesnt torned down the session)
plans for near future: implement most of tlvs
try to actually change an lsp's param (right now we just copy ero, which has been sent from
router to us in LSPrep and send it back in LSPupd for LSPs with delegated bit set)
add support for external source of topology (prob will be protobuf in redis, which we will grab)
and SPF calculation (not CSPF!) for sets of EROs
