Creation of BGP-LS speaker module and webUI interface to manage BGP-LS peers. Also, possibility to add discovered nodes and automatic link management. Creation of a folder in compute to support BGP-LS in NBI.

1) New features in BGP module.
2) Removal of old files.
3) Webui support for new functionalities.
4) Compute modification for NBI support (in progress).
