chore(updates.jenkins.io): add a dedicated File Share for httpd servi…

…ce (#676)

This PR adds a dedicated File Share for httpd.

This will allow us to mount the .htaccess file generated by
https://github.com/jenkins-infra/update-center2/blob/master/site/generate-htaccess.sh
and completed with
jenkins-infra/update-center2#776 only as volume
for the `httpd` updates.jenkins.io service, and every other files except
.htaccess as volume for the `mirrorbits` updates.jenkins.io service.
