Job.next_t (#1685)
* next_t property is added to Job class

Added new property to Job class - next_t, it will show the datetime when the job will be executed next time.
The property is updated during JobQueue._put method, right after job is added to queue.
Related to #1676

* Fixed newline and trailing whitespace

* Fixed PR issues, added test

1. Added setter for next_t - now JobQueue doesn't access protected Job._next_t.
2. Fixed Job class docstring.
3. Added test for next_t property.
4. Set next_t to None for run_once jobs that already ran.

* Fixed Flake8 issues

* Added next_t setter for datetime, added test

1. next_t setter now can accept datetime type.
2. added test for setting datetime to next_t and added some asserts that check tests results.
3. Also noticed Job.days setter raises ValueError when it's more appropriate to raise TypeError.

* Fixed test_warnings, added Number type to next_t setter

1. Changed type of error raised by interval setter from ValueError to TypeError..
2. Fixed test_warning after changing type of errors in Job.days and Job.interval.
3. Added Number type to next_t setter - now it can accept int too.

* Python 2 compatibility for test_job_next_t_property

Added _UTC and _UtcOffsetTimezone for python 2 compatibility

* Fixed PR issues

1. Replaced "datetime.replace tzinfo" with "datetime.astimezone"
2. Moved testing next_t setter to separate test.
3. Changed test_job_next_t_setter so it now uses non UTC timezone.

* Defining tzinfo from run_once, run_repeating

1. Added option to define Job.tzinfo from run_once (by when.tzinfo) and run_repeating (first.tzinfo)
2. Added test to check that tzinfo is always passed correctly.

* address review
