## Changes
1. Updated the list of bootnodes.
2. Merged the Connect node and bootnode into a single node.
3. Decreased the number of nodes.
4. Updated the DNS name.

## Description
The initial 8 bootnodes were planned to be replaced by community
bootnodes, the community node was added but we did not bother to reduce
the Parity managed bootnodes. Fixing it now.

# Description
Update the DNS name of bootnodes to unify the deployment. 

Each bootnode have 3 port exposed: `30333, 30334, 443`. Before, we had
different DNS names for `30333, 30334` and `443` ports. It may confuse
people and give the impression that it is two different nodes. Fixing it
by using a single domain for all

* add Rotko Networks to relay chain bootnodes

* add backed up key to westend
