Adding cellular connect/disconnect support

Change-Id: I40bbe3a4bdc94831c1fdf51eedddbeeca1c232e8

Including Cellular Connect/Disconnect support into the library.
Also adding the first test cases of text message receiving and verifying
that a notification window appears with the correct text.

Moved chromeos_wifi_sanity to chromeos_network_sanity so it makes sense
to add cellular test cases into the suite.

BUG=None
TEST=chromeos_txt_msg_functional.py
