examples/ip_pipeline: check VLAN and MPLS parameters

Browse Source 
This commit add to CLI command check for the following errors
1. SVLAN and CVLAN IDs greater than 12 bits
2. MPLS ID greater than 20 bits
3. max number of supported MPLS labels to avoid array overflow

It prevents running CLI commands with invalid parameters.
