MDL-47410 behat: Support selection from the datetime selector element

Adds behat support for selecting date and time from a datetime selector
element. The passed values should represent a textual date and time
description wrapped in '##' (e.g. '##first day of January 2020 08:00##',
'##1 Jan 2020 10:30##'). Also, the value 'disabled' is valid and can be
used to disable the datetime selector element.
