new setup for experiment4

[Szymon-Gut]

I have changed setup for rerun of experiment4. What is added:

• Now I have fixed problem with our implmentation that we can't specify epsilon decay for every task, so I firstly train agent on first task with appropriate epsilon decay and then I load him to second task overwriting his epsilon decay to value which matches current epsilon reset.
• Rest of files (I mean trained agents on first task and appropriate formats of meta files) I will send to Maciej who is responsible for eval impact on other platform to not clutter our repo
