Synchronize parameters with scenarios

[vadim0x60]

If, when I initialize BoptestGymEnv, I select a scenario like this:

env = BoptestGymEnv(
  start_time            = 0,
  scenario              = {'electricity_price': 'dynamic', 'time_period': 'peak_heat_day'})

this leads to errors and unstable behavior, because 'peak_heat_day' scenario includes a start_time and this start_time is not zero. So the request above (create a 'peak_heat_day' scenario with a start_time of 0) is inconsistent, however BoptestGymEnv doesn't raise any exception immediately, instead what happens is:

• the start time in dockerized BOPTEST simulator is set to 1382400, as specified in peak_heat_day scenario
• the start time variable in BOPTEST gym is set to 0 as specified in the constructor
• this conflict leads to hard to catch bugs down the line
