SG-36129 Add customized sort fields

[pscadding]

Makes the My Tasks tab sort fields configurable through the yml settings.

The user can choose any fields including linked fields to sort by, assuming that they are valid fields to sort by.

The default sort options are the same as before + the step which appeared to be mostly added by possibly accidentally excluded. (Note the UI styling looks a little weird here, because I'm running out of my terminal and not a DCC)

The user can then customise the list through the env config.

If its configured with a non existing field it will result in an error in the console if the user picks that sort field in the list.
I'm not sure there is a better way of handling this as it asynchronous so I can't just wrap the instruction to load data in a try except.
I think in order to get a better handle on it we might need to make changed to the shotgun model.
An example of the error you would get is here:

Looks good to me. I would also like to have better error handling for the case you pointed out. Is it possible to invest more time for it?

Also, I think the documentation should be updated as well. Probably this page.

Suggested change

	description: "Controls what fields appear for sorting
	"
	description: "Controls what fields appear for sorting"

[pscadding]

Actually I had intended to add more details there, that was just place holder. I'll update that thanks

[pscadding]

Also I wonder if the setting name should not be my tasks specific and then you list the tab under it. That way if we add the sort field to other tabs we wont need to change the setting name.

[pscadding]

I moved the sort order to the top, it was shown at the bottom of the list. This brings it inline with the web UI.

LGTM! Thanks for that @pscadding

We decided not to implement the changes on the SG Utils for better catching. We didn't want to introduce unnecessary risk for the handling of this edge case.
