Subject: [PATCH] wpa_cli: Add command for setting PSK_PASSPHRASE

Setting mem_only_psk=1 in the wpa_supplicant configuration prevents the
passphrase from being stored in the configuration file. wpa_supplicant
will request the PSK passphrase over the control interface in such case
and this new wpa_cli command can be used to set the psk_passphrase.

usage:
psk_passphrase <network id> <psk_passphrase>
