Allow configuration of asset urls for the login-server

https://www.pivotaltracker.com/story/show/72543482
Allow LDAP configuration for the UAA job. This allows configuration as uaa. properties and for backwards compability login. properties.
LDAP authentication has moved from login server to the UAA.
Remove ldap configuration from the login server. This is now handled by the UAA.
Keep ldap properties in spec, so that changes can carry over to UAA without a manifest change for backwards compatibility.
When configuring LDAP in the login server, we must remove the ldap profile since it will be taken over by the UAA
Allow the dbscheme to be included automatically if the profile is ldap alone.
Bump uaa and login-server to 1.7.0
Merge remote-tracking branch 'origin/pr/420' into develop
