Show the time it takes to fetch WITSML data for each view

[eliasbruvik]

When navigating in the application, we should show the time it takes for the WITSML query to complete.

For example, when opening the WellsListView, it should show the time it takes to fetch all the wells. When opening the CurveValuesView, it should show the time it takes to fetch the data in the provided interval.

For some views, we might be fetching different kinds of data at the same time (like fetching the wellbore in addition to fetching an object). In those cases we should show the time it takes to fetch the object, and not the "less important" fetches.

It is suggested to show this information at the bottom bar to the right, between the PropertiesPanel and the Desktop/Web Version.
