I'll revert and try to reproduce it locally to see what is going on.

Reland [Mojo Video Capture] Add integration test for crashing video capture process

PatchSet 1 is state as reviewed and reverted.
PatchSet 2 applies fix

Reason for revert:
The newly added test failed on chromium.linux/Cast Audio Linux with a timeout.

Description of fix
------------------
The test should not be run on that builder. Turns out all other tests of the same kind are conditionally build with build flag |enable_webrtc|. The fix moves/renames the test to match that pattern.

Original CL description
-----------------------
This CL is part of the Mojo Video Capture work. For the bigger picture,
see [1] CL27

Adds a content_browsertest RecoverFromCrashInVideoCaptureProcess, which does the
following:
1. starts video capture
2. verifies that video is rendered
3. finds and forcefully shuts down the process hosting the video capture service
4. verifies that video capturing and rendering stops
5. restarts video capture
6. verifies that it video is rendered again

In order to make this work, I added code for looking up browser child processes
from a string tag, which in case of services is supposed to be set to the
service name.
