[BUG] Aruba CX: BGP communities are not propagated over VRF EBGP sessions

[ipspace]

neighbor send-community has to be configured on VRF EBGP sessions as well

• Test topology: https://github.com/ipspace/netlab/blob/dev/tests/integration/vrf/16-vrf-bgp-community.yml
• Validation results: https://tests.netlab.tools/_html/arubacx-libvirt-vrf

that's strange...

Yeah, I have no idea what was going on. Now it works :(

Also, as of this moment, ArubaCX has zero validation errors ;) Great job!
