Move ldap.osgeo.org (secure container) from osgeo7 to osgeo9

[robe]

As discussed in #3178 osgeo7 is possibly unstable as it has gone down twice in the past 2 weeks. Moving secure to osgeo9.

I will start the process now.

This includes the move of id.osgeo.org as well, as I feel it's better for them to be on the same host since they are dependent on one another.

I've moved both secure and id-web containers and associated ldap.osgeo.org and id.osgeo.org hosts domains (registered in cloudflare of course).

I still have the osgeo7 secure running just in case things have not propogated yet. I plan to shut that down in a couple of days.

I still need to move over the cronjob that copy's the letsencrypt cert to secure container.

This is now complete. I decided not to wait that long. I have shut off secure on osgeo7 and did the following

1) Changed osgeo4 backup scripts to pull from osgeo9

2) Moved letsencrypt cron deployed via ansible to run from osgeo9

3) Completed removed certs with certbot delete (id.osgeo.org and ldap.osgeo.org) from osgeo7 nginx as well as the associated sites

4) Update wiki.osgeo.org: ​https://wiki.osgeo.org/wiki/SAC_Service_Status
