Present the 'misp_webserver_harden' variable

[egypcio]

Description

Present the misp_webserver_harden variable, so we avoid depending on juju4/ansible-harden-apache, should we plan to have a clean setup also serving HTTPS.

Motivation and Context

templates/apache2-misp.conf.j2 was set to enforce the use of https://github.com/juju4/ansible-harden-apache, should we ended up setting the MISP role to serve HTTPS traffic by default. There was no option available to disable the inclusion of a particular configuration file which hardens the Apache virtual host.

Here we work that out, and present misp_webserver_harden (set to true by default), which gives folks an option to disable that if they want to.

How Has This Been Tested?

After changing the misp_base_port to 443 (which would require setting up TLS certificates), we:

• Applied this role, against (fresh installed) Ubuntu machines using the particular versions affected by this change request;
• Verified the presence (or not) of a included file for the misp.conf virtual host.
