Route targets for L2VNI - #746

Conversation
Operators need explicit control over which L2 EVPN routes are exported and imported instead of relying only on FRR defaults. Add optional import and export fields, then propagate them through generated CRDs, manifests, and API documentation.

- Line 155: Update the route-target validation around the extended-community
check to parse the community values and compare complete route-target tokens
rather than using strings.Contains. Ensure an expected value such as RT:65000:1
does not match a longer value like RT:65000:10, while preserving successful
exact matches.

IMHO, we should take the opportunity and rename the existent vniConfigs to l3VniConfigs.
Same for the parameter - we should rename VNIs to L3VNIs.

nit: do we need to match the substring ? couldn't we match the full error ?

should we add another test, where one of the RTs matches, but the other doesn't ?
plus another with empty route targets.
Custom L2VNI route targets must reach FRR so operators can build selective EVPN import and export policies. Convert validated API values into FRR configuration while preserving default behavior when both lists are omitted.

Verify advertised Type-2 routes carry configured export targets and remote routes become reachable through matching import targets. This protects end-to-end policy behavior beyond generated FRR configuration. Route-target comparisons use complete extended-community tokens so a configured target cannot match a longer target prefix.

Is this a BUG FIX or a FEATURE ?:
What this PR does / why we need it:
L3VNI and L3VPN already allow for user provided rt export / import, adding to l2vni too.
