Testnet experiments: test for generating the baker partitions

Context

This script generates a list of files defining the associations between pods/nodes and bakers in testnet experiments. The list of baker aliases can be also retrieved from an output file via the following command:

cat $BAKER_PARTITION_FILENAME| jq ".[] | .alias" | tr -d '"' | tr '\n' ' '

which can then be used in conjunction with ./octez-baker-PtNairob to bake only for the bakers specified in $BAKER_PARTITION_FILENAME

Manually testing the MR

NODES=<nodes> OUTPUT_DIR=<output_dir> dune exec devtools/testnet_experiment_tools/testnet_experiment_tools.exe -- partition_bakers

Results are saved in <output_dir>.
