--------------------------------------------------------------
We've proceeded further with the review and here's the updated list of changes:
https://reviews.apache.org/r/44287/: Added MasterContender and MasterDetector abstract classes.
https://reviews.apache.org/r/44288/: Changed MasterDetector/Contender namespace.
https://reviews.apache.org/r/44543/: Removed unnecessary MasterContender and MasterDetector definitions.
https://reviews.apache.org/r/44544/: Moved contender and detector definitions into separate directories.
https://reviews.apache.org/r/44545/: Instead of keeping standalone and zookeper contender/detector class
definitions and implementations in the same file, separated them. Also
made the necessary changes in users of class headers to point to the
new locations.
https://reviews.apache.org/r/44546/: Moved functions in promises to a common header file.
https://reviews.apache.org/r/44547/: Added functions in promises to the collect header.
https://reviews.apache.org/r/44289/: Added support for contender and detector modules.
https://reviews.apache.org/r/44669/: Added createFromModule methods to MasterContender and MasterDetector.
https://reviews.apache.org/r/44670/: Added master_detector and master_contender flags.

> Currently mesos depends on Zookeeper for leader election and notification to slaves, although there is a C++ hierarchy in the code to support alternatives (e.g., unit tests use an in-memory implementation). From an operational perspective, many organizations/users do not want to take a dependency on Zookeeper, and use an alternative solution to implementing leader election. Our organization in particular, very much wants this, and as a reference there have been several requests from the community (see referenced tickets) to replace with etcd/consul/etc.
> This ticket will serve as the work effort to modularize the MasterContender/MasterDetector APIs such that integrators can build a pluggable solution of their choice; this ticket will not fold in any implementations such as etcd et al., but simply move this hierarchy to be fully pluggable.
