Wps default date

[sixlighthouses]

What this PR does

Fixes #6896 & #6895

Refactored the DateTimeParameterEditor to a functional component and added the terria object to the props, this allows the component to load with a default dateTime -- either the current time or if a timeline is loaded it takes the currently loaded time from that

Test me

Browse to
http://ci.terria.io/wps-default-date/#share=s-bRTdoGD1E1hSA95nLCVwIEjNXa9

From the My Data tab select the AWAVEA WPS service and then the Wave: Annual Bivariate Probability Distribution service

Select a point location, manually edit the start and end times. Update the times manually several times to test that the other unedited values do not change.

Ensure the debugging console is open on the Network tab, hit Run Analysis

confirm the Payload of the request has the Date Time correctly formatted as YYYY-MM-DDThh:mm

Upon loading the Analysis Tools, if the current Terria session has timeline loaded that time in the will become the default time in the dateTime inputs of the WPS process

@sixlighthouses - Thanks for your work on this!

Testing with no timeline:

• Default date/time does get set to current date/time in wps parameter form
• Manually changing dates or times works correctly

However, when if I set dates/times and then click on the map to get a location, the dates and times seem to be reset to the current date/time when the form reappears. Changing them back to what I had before seems to work but when I submit the form the start date/time value is messed up in the request that goes to the WPS:

e.g.

Testing with timeline shortly.

@sixlighthouses - testing with a timeline - the default date does get set to the currently selected value in the timeline but seems to be off by 1 day for some reason? (Am I missing something obvious here?). Check the following image:

Thanks for your work on this @sixlighthouses !

@sixlighthouses I think these changes look great. Thanks for taking time to refactor the component as tsx.

I have just left a couple of comments.

I think these need to go.
