Provide support for weekdays in timeperiods in PyNag format

[akimboyko]

Hi @Crapworks,

Here is an update for RESTlos validate function to support weekdays in timeperiods in the format supported by 0.9.1.1 version of PyNag.

For example:

[
  {
    "alias": "monday_and_friday_are_workdays",
    "name": "monday_and_friday_are_workdays",
    "timeperiod_name": "monday_and_friday_are_workdays",
    "monday              06:00-11:00": "",
    "monday              12:30-15:00": "",
    "monday              17:30-22:30": "",
    "friday              00:00-12:00": "",
    "friday              13:00-22:00": "",
    "friday              23:05-23:25": ""
  }
]

It is not a real workaround for that as it is not based on PyNag object_definitions. However, it is good enough for our internal purposes.

Other types such as days of generic months, days of specific months, and calendar dates could be supported also if there will be interest by the community

an initial version provides support for weekdays only

actual solution based on suggestion: use an if statement evereywhere to treat Timeperoids special from pynag issue 243
