* Implement actor field for tasks * Implement actor management in local scheduler. * initial python frontend for actors * import actors on worker * IPython code completion and tests * prepare creating actors through local schedulers * add actor id to PyTask * submit actor calls to local scheduler * starting to integrate * simple fix * Fixes from rebasing. * more work on python actors * Improve local scheduler actor handlers. * Pass actor ID to local scheduler when connecting a client. * first working version of actors * fixing actors * fix creating two copies of the same actor * fix actors * remove sleep * get rid of export synchronization * update * insert actor methods into the queue in the right order * remove print statements * make it compile again after rebase * Minor updates. * fix python actor ids * Pass actor_id to start_worker. * add test * Minor changes. * Update actor tests. * Temporary plan for import counter. * Temporarily fix import counters. * Fix some tests. * Fixes. * Make actor creation non-blocking. * Fix test? * Fix actors on Python 2. * fix rare case. * Fix python 2 test. * More tests. * Small fixes. * Linting. * Revert tensorflow version to 0.12.0 temporarily. * Small fix. * Enhance inheritance test.
