SR-TE LSP path computation using local CSPF

This feature introduces full CSPF path computation for SR-TE LSP paths.

The hop-to-label translation, the local CSPF, or the PCE path computation methods for a SR-TE LSP can be user-selected with the following path-computation-method [local-cspf | pce] command. The no form of this command sets the computation method to the hop-to-label translation method, which is the default value. The pce option is not supported with the SR-TE LSP template.
