Internal implementation of the puller API. Registers pullers by putting
them in the kAllPullAtomInfo map. Implements the actual pull,
with condition variables to timeout.
Lastly, keys the kAllPullAtom info by a PullerKey, which is a uid and
atom id. However, the uid is just set to a default of -1 for now. I will
work the security implementation in a follow up CL.
Test: builds, boots
Test: I will write unit tests in the future. It's very difficult to
write any without StatsEvent being completed.

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.

For pulled atoms, if use_zero_default_base is set to true, and if use_diff, the first data
piece will assume 0 value as base.
This requires a successful previous pull to set mHasGlobalBase.
mHasGlobalBase is reset when condition changes to false or we skip more
than 1 bucket.

This is to be consistent with other patterns such as UidMap.
This also makes unit test simpler.

+ change StatsPullerManager internal time units to be consistent
+ use series of alarms for pullers, instead of use setRepeating

all pullers have a default 1s cool down before next pull.
We can adjust these later.
Also add puller stats in StatsdStats
