Update network priorities before PNO is triggered
The max SSID watch list size for PNO supported by wlan drivers is fixed
to a certain size. wpa_supplicant sorts this SSID watch list based on
the priorities assigned to those networks. This may result in us losing
some frequently used networks from the PNO list because they have lower
priorities. This is a side effect of how we assign priorities to
network configuration as they're added.
So before we trigger PNO, re-sort the network list based on the
'numAssociation' value and assign them relative priorities. This will make
sure that the PNO SSID watch list contains all the frequent SSID's to
which we were connected to.
PS: This change has a side-effect of ignoring the configured priorities
during PNO.
While there,
1. Add a common test utils class for common utility functions for all
tests.
2. Annotate all tests in WifiConfigStore so that
|WifiTestUtil.getTestMethod| works reliably.
