ldapReadConnectTimeout and ldapReadTimeout fields break the plugin

[rabun788]

These two fields look to not be used, looks like this was prematurely pushed into master.

"ldapConnectTimeout": 3000,
"ldapReadTimeout": 3000

ex:

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "ldapReadTimeout" (class io.containx.marathon.plugin.auth.type.LDAPConfig), not marked as ignorable (10 known properties: "base", "userSearch", "groupSearch", "bindUser", "dn", "url", "useSimpleAuthentication", "userSubTree", "bindPassword", "groupSubTree"])
