test gateway as a replacement for tomcat@proxycas

[landryb]

items:

• as both the s-p & the gateway should be available in 24.0 (cf [GIP] Replace Security Proxy by new Gateway component improvement-proposals#8) it should be a toggle in the playbook
• gateway/security.yaml needs to be templated for at least ldap baseDn / admin dn/pass
• systemd unit for gateway microservice
• nginx vhost from switch from apache to nginx #127 should point to the gateway port instead of 8180 that was used by proxycas (or make gateway listen on 8180 ?)
• logging to /srv/log like other microservices
• what options to put in the env for spring boot startup ?

tested locally, needed this chunk for the gw to start:

--- a/gateway/routes.yaml
+++ b/gateway/routes.yaml

some headers are apparently needed for geoserver, otherwise going to https://georchestra.example.org/geoserver redirects to http://localhost:8380/geoserver/web (even with X-Forwarded-Host/X-Forwarded-Proto)

other than that logging in and loading console/geonetwork/mapstore seems to work. a toggle in the playbook to decide whether we want to use the s-p or the gw (and send traffic to 8180 or 8980 accordingly) is still needed

@pmauduit can you do a pr from the gateway branch rebased on master so that we can merge it ? please also grab the gwc bit from georchestra/datadir#397 ;)
