[code coverage] Turn on experiment for linux-coverage-rel to 10%

The linux-coverage-rel bot is relatively stable now, only 1 build failed out of the last 15 builds manually triggered by developers. A dedicated pool of 7 bots were created for linux-coverage-rel and 80 VMs were added to the main testing fleet, so enough capacity is ensured for 10% experiment for linux-coverage-rel. Following are the CLs that added capacity for this experiment: https://chrome-internal-review.googlesource.com/c/infradata/config/+/874989 https://chrome-internal-review.googlesource.com/c/infradata/config/+/867204 Bug: 930364 Change-Id: I4614e31f43217940fc841093fe98fbfb620f8cbb Reviewed-on: https://chromium-review.googlesource.com/c/1474549 Reviewed-by: Stephen Martinis <[email protected]> Reviewed-by: John Budorick <[email protected]> Commit-Queue: Yuke Liao <[email protected]> Cr-Commit-Position: refs/heads/master@{#633991}
