trafgen: parser: Add syntax for MPLS header creating
Add 'mpls()' function for creating MPLS header with parameters:
lbl|label MPLS label
last Indicates the last label on MPLS stack
tc|tclass|exp Traffic Class (TC)
ttl TTL (Time To Live)
Currently only unicast MPLS is supported, but multicast might be set
via 'eth()' function.
