/**
 * The change-master-password command.
 * This is a command which can operate on both the DAS and the node
 * The master password is the password that is used to encrypt the DAS (and instances) keystore. Therefore the DAS and associated server instances need the password to open the keystore at startup.
 * The master password is the same for the DAS and all instances in the domain
 * The default master password is "changeit"and can be saved in a master-password file:

 * 1. DAS: domains/domainname/master-password
 * 2. Instance: nodes/node-name/master-password
 * The master-password may be changed on the DAS by running change-master-password.
 * The DAS must be down to run this command. change-master-password supports the --savemasterpassword option.
 * To change the master-password file on a node you run change-master-password with --nodedir
 * and the node name.  The instances must be down to run this command on a node
 * 
 * If --nodedir is not specified it will look in the default location of nodes folder and find
 * the node
 *
 * If the domain and node have the same name it will execute the command for the domain. Incase
 * you want the command to be executed for a node when the domain and node name is same
 * you will need to specify the --nodedir option
