test and set directory_nodes

[openoms]

To test:

# for mainnet
directory_nodes_list=$(curl -Ss \
 https://raw.githubusercontent.com/JoinMarket-Org/joinmarket-clientserver/master/src/jmclient/configure.py \
 | grep MAINNET -A1 | grep 'directory_nodes =' | awk -F'=' '{print $2}' | tr -d ' ' | tr ',' '\n' | cut -d: -f1)
echo $directory_nodes_list
for i in $directory_nodes_list; do
  time torsocks nc -zv $i 5222
done

# for signet
directory_nodes_list=$(curl -Ss \
 https://raw.githubusercontent.com/JoinMarket-Org/joinmarket-clientserver/master/src/jmclient/configure.py \
 | grep SIGNET -A1 | grep 'directory_nodes =' | awk -F'=' '{print $2}' | tr -d ' ' | tr ',' '\n' | cut -d: -f1)
echo $directory_nodes_list
for i in $directory_nodes_list; do
  time torsocks nc -zv $i 5222
done

Would make a nice option in the TOOLS menu. Could also add the unused nodes to the joinmarket.cfg.

Also see https://github.com/JoinMarket-Org/joinmarket-clientserver/issues/1445 for new directory nodes proposed.
