Utils scripts should run using devenv services

[CAGS295]

Description

Utils scripts should run using devenv services.

Take for example mine_btc.sh

bitcoin-cli -rpcconnect=localhost -rpcport=18443 -rpcuser=devnet -rpcpassword=devnet generatetoaddress $num_blocks $btc_address

vs

$(dirname $0)/../bitcoin/bin/bitcoin-cli -rpcconnect=localhost -rpcport=18443 -rpcuser=devnet -rpcpassword=devnet generatetoaddress $num_blocks $btc_address

Context

For reference, look at the bin dir in the devenv's services. Bins are scripts that call docker run internally to access the binaries inside the services. This enhancement increases portability.

Expected Approach

Replace calls to the local host's binaries with docker run targeting the appropriate service.

Acceptance Criteria
