mpls-conf: T915: Add MPLS misc parameters, add LDP misc parameters

This commit has to do with the addition of miscellaneous MPLS parameters, as well as miscellaneous LDP parameters. Per c-po, for miscellaneous options and whatnot that do not fit anywhere we will put them into a specific "parameters" node.

I also did some global linux configuration changes here. We make changes to kernel options "net.mpls.ip_ttl_propagate" and "net.mpls.default_ttl" which should allow the behavior of VyOS to have the same as routers from the big vendors.

I added two LDP options for cisco interoperation TLV and for a dual stack preference.

Lastly, I went through and changes some of the help/description fields in the definitions page because I just felt they weren't uniform and the words seemed to not properly explain what they were doing. I also did some code clean up (or tried to...) with comments and whatnot.
