Add support for storing Openconnect secrets to KWallet
Review Request #122012 - Created Jan. 12, 2015 and submitted
This patch adds support for storing secrets to KWallet from Openconnect auth dialog, which is the only part where secrets could be stored. It should behave similar to nm-openconnect, which means that all secrets which are OC_FORM_OPT_PASSWORD are stored to KWallet or they are not stored at all. I know I should avoid using synchronous calls when opening KWallet, but in this case it would be probably complicated to use it asynchronously.
