* protect /connection url paths with permissions
These permissions match the original ones at /datasources and /plugins
* add Connections section to navtree only if user has permissions
This commit works only when the easystart plugin is not present.
I'll see what I can do when it is present in the next commit(s).
* update datasources page permissions
The datasources page have Explore buttons on datasource entries,
therefore it makes sense to show this page for those, who can't edit or
create datasources but have explore permissions.
This applies for the traditional Editor role.
* DataSourcesList: link to edit page only if has right to write
If the user doesn't have rights to write datasources, then it's better
to not create a link from cards to the edit page. This way they won't
see the configuration of the data sources either, which is a desirable
outcome.
Also, I moved the query for DataSourcesExplore permission out from the
DataSourcesListView component in the DataSourcesList component, next to
the other permission queries - for the sake of consistency.
* fix permissions for connect data
This way it matches the permissions of the "Plugins" page.
* fix applinks test
