Support searching on License start and end date

Purpose:
Find licenses based on when their start and end dates are, and find licenses that are lacking start or end dates

Description
Add options to search by start and end date into the Licenses search and sort screen

• Separate search options - one for start date, one for end date.
• The user should be able to specify a date on or after which the start/end date falls AND a date on or before which the start/end date falls - these constraints should be applied together. e.g. "find licenses with an end date on or after 1st January 2020 AND on or before 31st December 2020). Both the constraints are optional
• The user should be able to check a box to include licenses without a defined start/end date and this should be combined with the date constraints as an "OR". e.g. "find licenses with an end date that is either on or after 1st January 2020 OR is empty

See mockup

For the checkboxes use the phrases:

• Include licenses with no start date set
• Include licenses with no end date set
