Add nginx-ldapauth-proxy (#3013)
* Add nginx-ldapauth-proxy We created this as an authentication layer on top of our ELK stack. We thought it might be useful for other people as well. * Add sources and github usernames * Fix API version for deployment Add spec.selector matchlabels * Add release to selector matchLabels * Update metadata to nre release * Use new template for chart label * Fix app matchlabels for deployment * Move nginx-ldapauth-proxy to stable * Change default proxy service to kubernetes.default * Only enable ldap auth if ldapHost and ldapBindPassword are set * Make sure / is available * Add stub_status to status location in nginx * Remove superfluous $
