When enabled, allows masking passwords that may appear in the console.
Passwords to be masked are defined as Name/Password pairs:

• Password is aimed at containing a password to be masked from the console. Empty and blank values are not allowed (e.g. " ", etc.). This field is ciphered.
• If Name is set, then a build variable will be defined accordingly. This allows accessing the password by using the variable rather than hard-coding it in a field which is not ciphered (e.g. the ones of the Invoke Ant or Execute shell build steps).
