Check and change password

Changes

Resolves #3049

This PR adds support for checking password expiry date and for changing passwords.

New component: Password Manager

The password manager is a new IBM i component that can:

• Return how many days are left before the current user's password is going to expire and the expiration date
• Change the current user's password using a temporary Java program. The Java program is compiled on the IBM i, in a temporary folder that gets deleted after it's done. The program contains the old and new password so they are not printed in the output when it's called. It uses the JTOpen jar shipped with the OS to perform the change.

New Change password status bar action

A new Change password action located in the connection's status bar menu allows users to change their password the IBM i they's connected to.
The action opens a webview asking for the current password and the new password (twice, for confirmation).

This webview will also display errors occurring before submitting the form and after, if the password change program fails.

Password expiry check

After a user connects, a password expiry check is performed.
The check is performed once for any new connection, and it's performed again one week later (in case the expiry policy changes over time).

After the check, if the password expires in less than two weeks, a modal notification shows up and offer to change the password.

Clicking on Change password will open the webview above.

How to test this PR

1. Connect to an IBM i
2. Hover over the connection status bar and select "Change password"
3. Try to change your password

Password expiry - if you have a *SECADM profile to play with:

1. Create a dummy profile with PWDEXPITV(5)
2. Create a new connection and connect with this profile
3. The password expiry dialog must show up
4. Close the dialog
5. Re-connect
6. The dialog must not show up...until tomorrow

Can we use QSYCHGPW via SQL instead?

Thanks @SanjulaGanepola !
I extended the delay between two checks to two weeks if there's no expiration. And two weeks before expiration if expiration is greater than 2 weeks.
