bgpd: BGP troubleshooting - Add a keyword self-originate to display only self-originated prefixes when looking at the BGP table for a given address-family

Browse Source 
Add a keyword self-originate" to extend current CLI commands to filter out self-originated routes only

a\) CLI to show ipv4/ipv6 self-originated routes
	"show [ip] bgp [afi] [safi] [all] self-originate [wide|json]"

b\) CLI to show evpn self-originated routes
    "show bgp l2vpn evpn route [detail] [type <ead|macip|multicast|es|prefix|1|2|3|4|5>] self-originate [json]"
