Silent private key password failure

[Dylan Powers]

If an openvpn connection has the private key password set to "Ask for this password everytime", when an incorrect password is typed into the prompt upon connecting, rather than reprompt for the password on password failure (or immediately fail), nm-openvpn just reattempts the same password over and over for a minute.

The following is repeated in the logs every 2 seconds:
Oct 10 13:48:02 mubuntu nm-openvpn[27181]: NOTE: the current --script-security setting may allow this configuration to ca
Oct 10 13:48:02 mubuntu nm-openvpn[27181]: SIGUSR1[soft,private-key-password-failure] received, process restarting

The workaround is to wait a minute for some sort of timeout to occur or go into the settings and flip the "Ask for this password everytime" option to force a reprompt.

This appears to be similar to https://bugs.launchpad.net/ubuntu/+source/network-manager-openvpn/+bug/1693809 but focused purely on the incorrect password aspect.
