We use one alarm clock for all pulled atoms.
If metrics from different configs are not aligned,
the clock will be set to repeat at higher and higher
frequency, and consume a lot of battery.
Current implementation assumes a 5min minimum bucket
size. New metric start time is set to be aligned to
the start time of statsd in the next 5min.
So it will ignore events up to 5min.
align puller alarm to minute bundary
Test: unit test

+ StatsdStats is the global class that tracks the stats about statsd.
+ Added guardrail for classes that have a map which could potentially grow
unboundedly with the number of logs.
TODO: add unit tests & CTS for StatsdStats, and guardrail
add stats for pulled atoms.

2/ Init anomaly from config based on the public language.
3/ Unit tests for anomaly detection in count/gauge producer.
4/ Revisit the duration tracker logic.
Test: unit test passed.

1/ use string id/name for all metrics/configs/matchers.
2/ move alerts out of metric proto.
Test: unit test passed.

Note:
This is for value metric. The default operations is sum the diffs.
The test uses kernel wake lock, which also needs dimension by kernel
wake lock name.
The test is a bit cumbersome as it needs StatsCompanionService to do
the alarm, which is not exact alarm.
The internal state of a slice of bucket would look something like this:
4:ipc0000005e_727_android.hardwar
0 0
4:SensorService_wakelock
40 64
4:ipc0000005c_727_android.hardwar
...
Test: manual test on device.

Newly supported metrics examples:
1) Compute [Total|Max] duration of [an app] holding [ANY] wake lock while [this app] is in
[background] and [screen off], bucket size 30seconds, and slice output by uid.
2) Compute [Total|Max] duration of [ANY app] holding [ANY] wake lock while [this app] is in
[background] and [screen off], bucket size 30 seconds.
+ DurationMetric proto has a "what" which is a SimpleCondition. It defines the atom level start
and stop of the duration timer, and it has its atom dimension. e.g., for wake locks, the atom
dimensions wil be uid and wl name.
+ Now dimension is explicitly specified in SimpleCondition proto instead of inferred from the "link"
+ Added support for "Or" and "Max" through 2 layers of aggregation.
TODO: (1) The way we track slicedCondition in duration metric is not efficient. optimize!
(2) The output dimension should all use int32 instead of KeyMatcher. Fix in a future cl.
Test: Added some unit tests using gmock. Will add more unit tests.

Now we support following metrics:
<Duration> of [app holding a wake lock], while [*this app*] is [in background] [AND] [screen is off]
[Slice] the output by [app name, wake lock name], with bucket size [30sec]
+ Also added onDumpReport() api in MetricsManager, it can be called from client to fetch the data from
statsd
+ Also added command line tool to dump the StatsLogReport from all metrics for debugging.
+ Synced proto from google3. with a pending cl (cr/172359050)
TODO: We need to add tons of tests to test the Metrics. I will work on it after this CL so people
can be unblocked.
I locally test the duration metric with wake lock with an app that generates StatsLog events.
Test: statsd_test
and manual test, and run:
adb shell cmd stats dump-report
We have a default config, which contains a metrics to count PROCESS_START event sliced by
package name.

- Add a ConfigManager class that tracks the configurations
that have been passed to us. Configurations are now
tracked by tuples of (uid,tag), where the tag is an
app-defined string, in case a single uid has multiple
configurations.
- Move all of the initialization into StatsService.
- Get rid of the ability to have multiple LogListeners. Raw
events are now pushed directly into StatsService, which
can distribute them to the interested parties (and will
eventually be able to do the proper locking).
- Add Log.h, which sets our LOG_TAG correctly.
- Move some of the related files that I expect will grow some
into their own subdirectories.

+ also synced proto from google3 to fix the LogEntryMatcher proto
+ MetricsManager represents StatsdConfig, it's responsible for initializing and managing all
LogEntryMatcher, Condition, and Metrics. Start review from here.
+ Added more complete StatsdConfig initialization, including building the map for:
LogEntryMatcher -> Metrics
LogEntryMatcher -> Condition
Condition -> Metrics.
All the maps use index(int). The extra amount of memory for storing mappings help us
quickly process log events.
The StatsdConfig initialization process detects malformed config
- Circle dependency
- Missing definition
etc.
And once we detect ANY error, statsd will reject the config. And the resources related to this
config will be released.
Test: Added unit tests
