Warn or require user to enable HTTP(S) access when enabling Git LFS

Problem Definition

It's currently possible to enable Git LFS in Bitbucket Server without having to enable HTTP(S) access. Git LFS requires HTTP to be enabled, however this may not be obvious to users as Bitbucket gives no indication that this is the case

Suggested Solution

If Git LFS is enabled but HTTP(S) access is not, display a warning to the user, or prevent the user from saving without correcting this configuration option.
