Adjust the cache rules showing mailing list subscriptions
---------------------------------------------------------

<beuno>
I had the following problem:
- Someone signs up for a mailing list
- I look at the current subscribers and that person isn't listed, however,
  they can see that they *are* subscribed
- Disabling the edge redirect and going to production shows the updated data

I waited for at least 10 minutes for this to be updated.

<sinzui>
We just completed our query optimisations for this page so we can consider
changing the cache rules. I propose caching for 10 minutes for anonymous users
only. Logged in users are working so they expect to see changes.

We should also update +participation since its queries were also updated. We
should use anonymous as well because logged in users are currently getting a
private cache, which is not very helpful.

Rules
-----

    * Update +subscribers to cache anonymous only.
    * Update +participation to cache anonymous only.

QA
--

    * Visit your +participation page as an anonymous user.
    * Follow a link to a team that you are subscribed too.
    * View the list of subscribers and find yourself.

    * Visit your +participation page as yourself.
    * Follow a link to a team that you are subscribed too.
    * View the list of subscribers and find yourself.
    * Return to your profile page and choose edit emails.
    * Unsubscribe from the list under test.
    * Visit your +participation page as yourself.
    * Verify you are not listed as subscribed.
    * Visit the team and look at the subscribers page
    * Verify you are not listed.

    * Visit your +participation page as an anonymous user.
    * Verify you are still listed as subscribed
    * Follow a link to a team that you are subscribed too.
    * View the list of subscribers and find yourself.
    * Wait 10 minutes.
    * Visit your +participation page as an anonymous user.
    * Verify you are not listed as subscribed.
    * Follow a link to a team that you are subscribed too.
    * View the list of subscribers verify you are not in the list.

Lint
----

Linting changed files:
  lib/lp/registry/templates/person-participation.pt
  lib/lp/registry/templates/team-mailinglist-subscribers.pt

Test
----

No tests changed. The existing tests verify that cache rules are present,
but they do not concern themselves with the exact condition.

Implementation
--------------

Changed the cache to anonymous, 10 minutes in:

    * lib/lp/registry/templates/person-participation.pt
    * lib/lp/registry/templates/team-mailinglist-subscribers.pt
