Merge branch 'shell_queries' of https://github.com/garraflavatra/mongodup into shell_queries

This adds a 'Log' view to the host panel using the [`getLog`
command](https://www.mongodb.com/docs/manual/reference/command/getLog/).

+## Feature list
+
+At this point, Rolens is comparable to MongoHub regarding features. It cannot handle things like user management _yet_, but it _does_ have:
+
+* Connecting to hosts
+  - Host status
+  - System info
+* Database management
+  - See stats
+  - Create dumps with `mongodump`
+* Collections
+  - See stats
+  - Find, insert, update, & remove
+  - Save queries to reuse them
+  - Customizable table view for query results
+  - Versatile forms to enter data in a standardized format
+  - Aggregation pipeline editor
+  - Fully customizable export to a number of formats like JSON, CSV, and Excel
+  - Index editor

 To obtain a copy of the source code, do either of the following:
 
 * Download a tarball or zip archive from the [release page](https://github.com/garraflavatra/rolens/releases/latest). Make sure you download the source archive, and not a pre-compiled binary.
