We don't know why this happens, so this is an attempt to debug the
issue by sending a full list of all columns ActiveRecord knows about
when the error is raised.

In this commit, some methods that aren't being used
are removed from `Gitlab::Shell`. They are the ff:
- `#remove_keys_not_found_in_db`
- `#batch_read_key_ids`
- `#list_key_ids`

The corresponding methods in `Gitlab::Keys` have been
removed as well.

Add a supporting code to separate groups#show
and groups#details which is required for the
proper implementation of the Group Overview
content and Security Dashboard option for it
