Make Qt Creator remember passwords

It is said that "Note: Qt Creator does not store passwords, so if you use password authentication, you may need to enter the password on every connection to the device, or, if caching is enabled, at every Qt Creator restart" according to our documenation:
https://doc.qt.io/qtcreator/creator-developing-b2qt.html

But we may want to let QtC remember password in future releases to streamline the deployment.
