wifi_prov_manager: Delay the Wi-Fi connect call
wifi_prov_manager: Delay the Wi-Fi connect call

For SoftAP provisioning, if we start Wi-Fi connection as soon as the
apply config request is received, it has been observed that the clients
(Phone apps mostly) do not get the response for this as we switch the
Wi-Fi channel, causing a momentary disconnection.

Delaying the connection calls helps mitigate the issue.
