To update Bitcoind in nodes

Follow these steps:

1. In /app/models/node.py, update the BU_VERSION contant.

2. In /scripts/update.sh, update the BITCOIN_URL.

3. In /scripts/update.sh, update the default subversionOverride version in bitcoin.conf. It starts with: net.subversionOverride=/BitcoinUnlimited

4. Update bitcoind on the node, as follows:

node = Node.query.get(10)
node.update_bitcoind()

Or, if you want to do it for all nodes:

nodes = Node.query.filter_by(status='up')

for node in nodes:
    node.update_bitcoind()
