## What do these changes do?
Fix the misleading comments in code for:
- `EPISODES_THIS_ITER`
- `EPISODES_TOTAL`
Had noted it before and planned to fix it along with some other changes but seemed very relevant to stay next to #3058 so sending this now.
This commit fix some small defects.
1. Remove a comment that should have been removed in #3003
2. Remove `redis_protected_mode` that is never used in `ray.init()`
3. Fix `object_id_seed` that is forgotten to be passed into `ray._init()`
4. Remove several redundant brackets.
This tests the case in which a worker is blocked in a call to ray.get or ray.wait, and then the worker dies. Then later, the object that the worker was waiting for becomes available. We need to make sure not to try to send a message to the dead worker and then die. Related to #2790.
Adds a tmux flag that can be used to support background execution of experiments. Cannot be used together with screen. Seems to be useful feature that has shown up with different users.

A fix to an example for tune (`python/ray/tune/examples/pbt_tune_cifar10_with_keras.py`) where the hyperparameters for the optimizer, learning rate and decay, were not being passed into the optimizer.
This means that the current optimizer uses default values for the hyperparameters no matter the config.
Add new search algorithm (genetic) along with the base framework of the searcher (which performs some basic jobs such as logging, recording and organizing in our project).
Note that this is the initial commit. In the following days, we will add example, UT, and other refinements.
When running in a screen (or any other time it is hard to scroll up), printing "Suppressing previous error message" is not helpful since the previous error is lost far above past scrollback. Better to just print it repeatedly at the end.
