test-case: add pulseaudio playback and capture test

[fredoh9]

Using pactl and pacmd sink or source can be set. paplay and parecord are
pulseaudio utility for playback and capture respectively. PulseAudio
should be enabled before the test. paplay expects actual audio file, dummy
file cannot be used.

Tested with GLK_BOB_DA7219. This is PulseAudio sinks and sources in the DUT. That's why i did some grep and find indexes. sink index = [0, 1 ], source index = [2 ,3].

ubuntu@glk-bob:~$ pactl list short sources | grep sink

If PulseAudio is disabled, pulseaudio error will occur.

@fredoh9 Thanks for the new test. But I think we may need a good solution about when to enable pulseaudio and when to disable the pulseaudio. This will include pulseaudio status check, UCM file validation, pulseaudio switch function, pcm inuse check and etc.
@Bin-QA Could you help to work with @fredoh9 to make some solution for this? I will create a issue for this.

@fredoh9 How about add pactl effect check into lib.sh then if this function check failed, this case direct report exit 2

Thank you for comment. I can do that. When we are ready with pulseaudio utils, let's address changes at same time.

close this for now
