New Lines Behaviour in Markdown

Per markdown specification, only render line-breaks when you end a line with two or more spaces.

First close merge requests that being merged. Then update code of open
mr. This fixes bug when MR merged via command line lose their diff
because code reload was before MR close.

By opening the LDAP connection at the controller level we can reuse it
for all LDAP queries during the request.

This new method wraps Gitlab::LDAP::Adapter.open to enable connection
reuse.

This new method is based on Net::LDAP.open, which reuses a single LDAP
connection.

Removes the "Removing gitlabhq" messages cluttering spec output
