Battery attribute & accuracy filter

[GoNzCiD]

Breaking Change:

• battery_level attribute changes to battery.
  Since a device_tracker component contains a standart attribute for battery level, that we can use with see service, update with async_see method, we should use it for maintain component criteria and not create a new attribute for the same pourpose with a different name.
  To solve this breaking change, only need to replace the battery_level attribute with battery in all templates than use the battery attribute of any traccar device_tracker.

Description:

• Battery attribute is sent into see method instead of an additional paremeter.
• Added an accuracy filter option to exclude positions if accuracy is higher than specified.
• Added a skip accuracy filter option to avoid filter certain positions by accuracy if any of the specified attributes are present in the message, ie throw an alarm but accuracy is too high.
• Extract constants to const.py file.
