Issue 5311 - Add/remove columns in tickets table

[Amantini1997]

This fixes #5311

Description

• This template enhanced tickets table to show ALL the all the properties (that can be rendered as a text) from a given template (previously it was only some specific ones);
• Because of the previous point, all the tickets are fetched in full (previously, only the necessary properties were fetched), so that the tickets display the values for each filled property;
• There is now a feature to show/hide columns: a gear (rendered at the end of the columns headers) acts as a trigger for a dropdown menu listing all the template properties. To improve the UX, checking/unchecking a property from that list will show/hide the respective column in real time, but the modal will not move.

Bug(gish) behaviour

• The search feature does not work well. This is, however, acceptable as such a feature will be ditched with the new filtering system that is currently being brought to tabular view.
• Some safetibase properties were using special chips instead of plain text. This behaviour was intentionally changed to create consistency.

Test cases

Change template:

• the table should stretch to fit the screen;
• all the available columns (that have not been hidden by the user) should be available;
• the width of the new columns should be the default one, whereas the already available columns should keep the same width (unless a stretch takes place)
• switching to a new template that has all its columns hidden should show the id column

Change grouping options:

• the columns visibility and width shouldn't change

Change some ticket properties values:

• the columns visibility and width shouldn't change

Click the gear icon and:

• check/uncheck some properties. The respective column should show/hide;
• change a column width (remember this width, let's call it "Width A"), then hide and show again that column. The width should not change due to the hide and show flow (Width A).
