Add LDAP key sync to CHANGELOG-EE

LDAP key logging

See merge request !125

For some reason I needed to add a reload statement in the specs.

This allows us to keep Person#entry private, and it makes
Access#update_ssh_keys a little shorter.

Synchronise SSH keys with LDAP + specs

Please see MR !7 for reference.

Please see http://feedback.gitlab.com/forums/176466-general/suggestions/5704654-synchronise-ssh-keys-with-ldap for reference.

I added specs as well as fixed some bugs.

This MR is made of two (squashed) commits on purpose, as it is the only fair way to give @jolla credit for his work too.

Squashed commits:
[812406c] fixes bug from last refactoring
[53e9508] hides "delete" button if a key is a LDAPKey
[bafc66b] refactores update_ssh_keys in own method
[7895858] makes name of ssh public key configurable

This is done by using a separate LDAPKey model (inherited from Key)
for storing SSH keys which came from LDAP.
These keys can be viewed from user profile, but they can not be deleted.

Squashed commits:
[52b3816] Made SSH key synchronisation with LDAP configurable.

Now it can be turned on or off using configuration option
sync_ssh_keys in ldap section.
The default is off to preserve compatibility with old behaviour.

[02f988d] Synchronise LDAP users SSH keys from LDAP automatically.

upon login attempt and during regular LDAP security checks.
New keys are added, old keys not present in LDAP are deleted.

synchronise admins from LDAP group

from http://feedback.gitlab.com/forums/176466-general/suggestions/5738973-make-all-members-of-ldap-group-gitlab-admins :
> Make all members of LDAP group GitLab admins
>
> In GitLab EE it would be nice if you could make everyone in a certain LDAP group GitLab administrators.
>
> For instance, you would have a LDAP group 'GitLab admins' and anyone added to that group would automatically become admin in GitLab.
