This introduce the generic MPLS support
- New database tables for MPLS LSPs
- actually discovery and polling on NOKIA SR OS (Timetra) devices
- new routing->MPLS HTML pages

- ToDo MPLS LSP paths table and views
Suggestions and improvements are welcome

* add db schema

* some fixes

* add path table, discovery and polling

* add path views

* add test data

* Convert MPLS module to new style
Implement a SyncsModels trait to simplify code a lot

* abs() for negative value from snmp (bug?), test data
