This change establishes a place for perf experiments and adds a script to delay experiments for recovery purposes. For more info see go/pixel-perf-experiment-whatif. Bug: 365855872 Test: build/flash, set .Perf__experiments_delay_seconds=10, verify that vendor.perf.allow_experiments=1 after 10 seconds Flag: NONE controlled by Mendel instead Change-Id: I78db482542066d5d5646d8c303dbe88054cfe66d Signed-off-by: Dmitry Skiba <dskiba@google.com>

# This script delays experiments by the specified amount of seconds. The delay is not needed for
|
|
# the normal operation, but becomes essential for the rare case (which "should not happen") where
|
|
# an experiment causes really bad issues (e.g. crashes the kernel). In such case the delay gives
|
|
# GMSCore an opportunity to fetch fresh experiments snapshot (with the bad experiment disabled).

# See go/pixel-perf-experiment-whatif for more info.
