Overall flow of implementation:
1. parsing the config in MetricsManager to store the uids per atom. It
follows the mAllowedLogSources logic very closely
2. MetricsManager register itself as a PullUidProvider with the
PullerManager.
3. Metrics pass the config key when pulling (for both registering
receivers and normal pulls) , and the puller manager gets
the allowed uids from the PullUidProvider for that config.
4. PullerManager keys receivers by <atomId, configKey> so that it can
look up the uids for that atom using the PullUidProvider as well.
5. Added shell subscriber support. Hardcode a default of AID_SYSTEM for
them and also allow packages per atom. This involved adding a second
interface to Pull that simply accepts the uids, since I didnt want to
make the ShellSubscriber a PullUidProvider as well.
6. Change adb shell cmd stats pull-source to allow users to specify a
package. Default to AID_SYSTEM as well.
Notes:
The feature is flagged off right now, since configs do not pass in the
desired package. Another approach could be to hardcode in the current
mapping, but that doesn't work for OEM pulled atoms.

Because we no longer linkToDeath against a binder object to detect if
the cmd process has died, we detect deaths by checking if writes fail.
ag/10476582 proves that writes fail if the cmd process dies.

Major changes include:
- Removing unused permission checks within StatsService. These
include ENFORCE_DUMP_AND_USAGE_STATS, checkDumpAndUsageStats,
kOpUsage, and kPermissionUsage.
- Converting from sp to shared_ptr
- Using libbinder_ndk functions instead of libbinder functions
(e.g. for installing death recipients, getting calling uids, etc.)
- New death recipients were added in StatsService,
ConfigManager, and SubscriberReporter.
- Using a unique token (timestamp) to identify shell subscribers
instead of IResultReceiver because IResultReceiver is not exposed by
libbinder_ndk. Currently, statsd cannot detect if perfd dies; we
will fix that later.

1) Refactor pullers and add tests.
2) Add timeout to a puller.
mPullTimeoutNs is intrinsic to puller. A pull taking longer than this is
deemed failed and the data discarded.
A metric or StatsPullerManager requesting a pull should monitor the pull
and have deadlineNs. A successful pull may come later than desired due
to statsd processing delays.
3) Add unit tests to puller now that the base puller is more
complicated.

+ Changed the output format from Atom to ShellData, which is a wrapper for repeated Atom
This is useful because pulled atoms are usually a list of atoms.
