v0.7.8 p2p seednode and vrsc update

[smk762]

I guess its a good time to update VRSC also, will wait until API is released to see whats the latest.
PR is just draft/template until then.

Related PRs:

• update ports for next API release smk762/notary_docker_3p#50
• P2P release update GLEECBTC/seednode_docker#3

The p2p update in https://github.com/KomodoPlatform/komodo-defi-framework/ will result in a new netid, seednodes and tcp/ws ports. These may need to be updated manually by NN ops.

API release not yet ready, VRSC had just released another mandatory update with a 24hr warning. This will be implemented in a separate PR
