Matomo role assumes port 8000 for trusted host settings

[dannylamb]

Another gem from spinning up http://future.islandora.ca:

We assume port 8000 in the matomo role here. We should probably just rely on the site url that's already in config.

Looks like trusted host settings don't want the schema, so matamo_site_url might not work.

We could just add the port to the matamo_host variable and add a matamo_site_schema to store the http or https, then edit:

• matamo_base_url
• matamo_site_url
• and the above mentioned trusted host setting to make use of these two variables
