You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_cosmosdb_mongocluster_update'.The syntax is: az cosmosdb mongocluster update --cluster-name
                                --resource-group
                                [--administrator-login]
                                [--administrator-login-password]
                                [--server-version]
                                [--shard-node-disk-size-gb]
                                [--shard-node-ha {false, true}]
                                [--shard-node-tier]
                                [--tags]. The 1th example of the child command would be to use it to 'update a mongo cluster', the syntax is: az cosmosdb mongocluster update \
