Configurable default context for merge requests
Description
Currently, the default amount of context that is provided for the diffs when viewing files in a merge requests is +/- 3 lines.
This setting should be configurable.
It is possible to expand the view and see more context but it would improve usability to reduce the amount of manual expansion required. This is especially true for teams who may have used other diff tools that provide different amount of context by default.
I am not sure whether this is best set at a user level, group level or this being a server configuration. I think all would be a step in the right direction.
