mlaunch: Sharded Cluster creation fails

[rhysmeister]

A previously working command to create a MongoDB sharded cluster with mlaunch started failing a few days ago.

Expected behavior

I expect the sharded cluster to be created.

Actual/current behaviour

The mlaunch command fails with the following error...

b"BadValue: security.keyFile is required when authorization is enabled with replica sets\ntry 'mongod --help' for more information\n"
can't start process, return code 2. tried to launch: "mongod" --replSet shard01 --dbpath "/home/runner/work/mmo/mmo/data/shard01/rs1/db" --logpath "/home/runner/work/mmo/mmo/data/shard01/rs1/mongod.log" --port 27018 --fork --auth --shardsvr --wiredTigerCacheSizeGB 1

Steps to reproduce the actual/current behaviour

mlaunch --replicaset --sharded shard01 shard02 shard03 --auth --username admin -***

Environment

Software	Version
mtools	latest
Python	3.6 & 3.8
MongoDB server	4.0, 4.2,4.4,5.0
Operating system	ubuntu-latest

Hi @rhysmeister, keyFile was removed in PyMongo 4, replaced with tlsCertificateKeyFile. We missed the --keyfile CLI option when migrating mtools for PyMongo 4 support.

I think this may be a related one:

This is fixed in the develop branch for next release of mtools.
