Frequent exceptions on Linux ChromiumOS Tests (dbg)

Project Member Reported by warx@chromium.org, Jan 27 2017 
https://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%20Tests%20%28dbg%29%281%29

Recently there are a bunch of purples on Linux ChromiumOS Tests (dbg).

Errors are: Either it ran for too long (hard timeout) or it didn't produce I/O for an extended period of time (I/O timeout)

Missing results from the following shard(s): 3

This can happen in following cases:
  * Test failed to start (missing *.dll/*.so dependency for example)
  * Test crashed or hung
  * Task expired because there are not enough bots available and are all used
  * Swarming service experienced problems

Please examine logs to figure out what happened.

By discussing with bpastene@, this might be the issue on browsertests, or we can try increasing the number of shards ran for it on that bot.

Assigned to me first.

As I looked at  issue 414808 , 

in the reporter's description: need the ability to specify different sharding value per builder (i.e. debug Windows is ~5x slower than release because of all the extra asserts that catch bugs. so we might want 5 shards for release bots like we have on trybots, but 25 for debug). we'll need this ability for asan trybots as well.

For Linux ChromiumOS Tests (dbg), we may want to increase the number of shards.

Increase shards level for browser_tests on Linux ChromiumOS Tests (dbg)(1)

Changes:
Linux ChromiumOS Tests (dbg) is slower than release bots. So try to increase the number of shards here to see if recent timeout exceptions on  crbug.com/686265  could be fixed.

Status: Fixed (was: Assigned)
Since after build #21934 (which this CL is) there are no more exceptions happening, mark it as fixed.
