Logs improvements

[jordibc]

• Create a LogDialog component that encapsultes the log view.
• Have a paging mechanism so more logs can be shown.
• Show 'Loading...' at the beginning instead of the previous layout
• Be more specific with the logging. Describe the exact actions
• When displaying logs for a specific dataset, we shouldn't display the dataset in each entry. Probably better to display on the header -> we keep it as there could be several datasets affected by an action, and we want to see them all (even if they are not selected)
• Only log a change in the sharing settings if there are actual changes -> see note below

As discussed, @jordibc will work on the paging mechanism and create a PR just for that. Jordi if you can also add the third task (Show 'Loading' on init) to that PR it would be great. I guess it should be pretty straight-forward

To only log a change in the sharing settings, it seems we would have to modify d2-ui/lib/sharing/SharingDialog.component.js:98:

        this.props.onRequestClose(_sharing2.default.getState());
->
        this.props.onRequestClose(_sharing2.default.getState(), this.status.sharingChanged);

with a new variable sharingChanged that is set to true if the sharing properties actually changed.

Then, in dataset-configuration/src/DataSets/DataSets.component.js:394:

                    onRequestClose={() => {
->
                    onRequestClose={(state, sharingChanged) => {

and only call log() if sharingChanged.

• Sharing: Move logging to parent component, so it logs only once when dialog is closed.
