Provide a way to set a custom password on emulator creation

[XiaoGuo, Liu]

Currently, when our emulator is firstly powered on, it is asked to provide a pincode to login. The default one is "0000". However, it is very difficult or obvious to the developers. If the developer has not read any documents or is told the pincode "0000", it will take quite some time to guess it.

When creating the emulator, the developer should be prompted to supply a pincode to generate the emulator so that the developer can later use the pincode to login to the emulator.

Now it could prompt set the pincode, but after that it can't login with the pincode which I set, and the valid pincode is still '0000'.

[Oliver Grawert (ogra)]

it should instead print the pincode in the terminal where you create the emulator instance and the wizard should skip the pincode page ... (you can at any point change it using the "passwd" command btw)

(making this interactive and optional will break automation)

[Benjamin Zeller (zeller-benjamin)]

Why should that break automation? If no other value is given it just
falls back to the default value "0000".

When running emulator creation from QtCreator, reading the terminal output
is not really straightforward. Instead we should provide a way to set a custom password
and if none is given just fall back to the default password 0000.
