1. Add abseil-cpp as a submodule. We are tracking the latest LTS release, which is lts_2024_01_16. 2. Replace glog/gflags with absl::log and absl::flags. 3. Remove miniglog 4. Also take a whack at making the bazel build work with abseil-cpp and gtest. There are a number of TODOs in this CL that still need to be resolved. Change-Id: I39355ed7d61375be4ebcbc8596d9cc70acc1c678
