So far, tiles have been stored on disk which, in combination with
bad disk performance, made the map slow and laggy.
This patch switches to memcache, which will remove the dependency
on disk performance for loading cached tiles entirely.
Note that installing and configuring memcached will be required
manually like for the other dependencies.

There should be no installations of the mongoDB-based Monitoring
left, so the upgrading instruction seem useless and might actually
be even misleading.
Remove them.
