Improve relayer deployment with Docker

[karim-en]

Use Docker to deploy the relayer with light BTC node

• Find a good docker setup for bitcoind eg this
• Run the bitcoin node in Pruned mode to limit the disk usage
• Run the relayer and the node with one script or Docker Compose.

An example of complex Docker setup

@olga24912 can you please share your local setup, which node and mode have you used?

It seems that, specifically for Bitcoin, I didn't use any tricks and just followed the instructions: https://bitcoin.org/en/full-node#linux-instructions

Download: https://bitcoin.org/en/download

Install: sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-27.0/bin/*
In bitcoin conf (bitcoin-27.0/bitcoin.conf) I add:
server=1
rpcuser=user
rpcpassword=password
prune=2000

Copy conf:
cp bitcoin.conf ~/.bitcoin/bitcoin.conf

Run:
bitcoind -testnet -daemon

And just wait for sync

Either need to move this to "On Hold" or create a separate task for doge/zcash
