Install cheapseats over HTTPS instead of git

The deployment machines don't have access on the port that the git
protocol uses, so switch to a more normal TCP port.

We could use SSH for this too, but using HTTPS means that there's no
SSH key exchange needed.
Added improve dashboard message to the footer.

Config driven for high transaction services.

Fix bug in completion rate modules: pass filter params.

There was a bug in the student finance dashboard: filter parameters
had been specified for the completion rate modules, but were not
being passed through to the query. Fix this and update tests.

Interestingly, it looks as though the completion module does have
an option to set query parameters directly on the module, though
this wasn't being used. However, I suggest just using this quick
fix for now, and following up by reviewing the use of query
parameters across the whole of Spotlight - it would be good to
rationalise the way we handle them.

Links should be blue.

The underline might be enough in other circumstances, but here it looks like we're just underlining the heading.

I was prompted today - Matt mentioned that Lindsey from Student Finance
hadn't noticed the module pages existed at all. I think this will go some
way to fixing that problem, and is better than adding a 'more details' link
to every module.

Next, blue clashes hard with the blue-green, so we also lose the blue-green.

Allow configurable weekly periods for KPIs.

Most KPIs are monthly, but the waste carriers dashboard supplies
cost data weekly.

Extend the KPI module to handle this nicely.
