implement extended status call for iOS devices and simulators

[vdelendik]

in additions to the syncZebrunner services status ./zebrunner.sh status should return state of each whitelisted device/simulator and their services:

• appium
• wda
• stf

better to implement together with #54

[vdelendik]

done. we can track 3 states as of now:
disconnected, healthy and unhealthy.

testing should cover such scenarios:

1. status is displayed right after the start

./zebrunner.sh start
Waiting while services are up&running...

iPhone_8 (b09fa26acc4c3f777e9b8b49e3348b7243f862b5) is disconnected!
iPhone_14_Pro (E7916230-C08C-43E4-933A-9B4F1ECFB989)
iPhone_14 (44568699-BA22-4A88-8DD5-413AC1663051)

iPhone_8 (b09fa26acc4c3f777e9b8b49e3348b7243f862b5) is disconnected!
iPhone_14 (44568699-BA22-4A88-8DD5-413AC1663051) is healthy.
iPhone_14_Pro (E7916230-C08C-43E4-933A-9B4F1ECFB989) is healthy.

2. just verify status at runtime:

./zebrunner.sh status
iPhone_8 (b09fa26acc4c3f777e9b8b49e3348b7243f862b5) is disconnected!
iPhone_14 (44568699-BA22-4A88-8DD5-413AC1663051) is healthy.
iPhone_14_Pro (E7916230-C08C-43E4-933A-9B4F1ECFB989) is healthy.

3. verify status using concrete device udid:

./zebrunner.sh status 44568699-BA22-4A88-8DD5-413AC1663051
iPhone_14 (44568699-BA22-4A88-8DD5-413AC1663051) is healthy.

4. verify status over stopped services

./zebrunner.sh stop
Stopping MCloud services...
iPhone_8 (b09fa26acc4c3f777e9b8b49e3348b7243f862b5) is disconnected!
iPhone_14_Pro (E7916230-C08C-43E4-933A-9B4F1ECFB989)
iPhone_14 (44568699-BA22-4A88-8DD5-413AC1663051)
MCloud services stopped.
