Why not use stable version of abseil?

[zjuturtle]

I notice in WORKSPACE, there is a TODO

# Head commit on 2019-04-12.
# TODO: Switch to the latest absl version when the problem gets
# fixed.

What is the problem exactly?

There is an inconsistent Bazel config setting between mediapipe and abseil. Does the current abseil dependency cause any problem to you?

Moreover, abseil has three LTS versions (lts_2018_06_20, lts_2018_12_18, and lts_2019_08_08). Do you suggest that MediaPipe needs to depend on abseil's lts_2019_08_08? We avoid depending on the master branch of abseil since any changes in the master branch invalid the build cache and everything needs to be rebuilt again.

Currently I have not encountered any problem, it is just a little wired to use a snapshot version dependency. I think I'll suggest to use lts_2019_08_08 version.
Thank you!
