Debugging and log verbosity

novops is a Rust compiled binary. You can use environment variable to set logging level and enable tracing:

# Set debug level for all rust modules
export RUST_LOG=debug # or other level :info, warn, error

# Enable debug for novops only
export RUST_LOG=novops=debug

Show stack traces on error:

export RUST_BACKTRACE=1
# or 
export RUST_BACKTRACE=full
