FIX /static/ alias for Apache config

[sbancal]

/static/ alias in Apache config doesn't match with other configs (like nginx) ... and doesn't match the files. Fixing it.

Sorry, @sbancal , but that's wrong. Not sure about which Nginx config do you mean, but /opt/graphite/static/ is right path, jou just need to run collectstatic Django command, as described in documentation - see STATIC_ROOT in https://graphite.readthedocs.io/en/latest/config-local-settings.html

In my attempt to make installation easier, I'm trying to get rid of the whole collectstatic mess and serve static files with whitenoise from the application as default. Then you also won't need to configure the webserver for serving static files, which makes it even easier.

We'll still have an option to serve static files from a webserver, but using whitnoise as default should be good enough for most installations, especially since I expect most users running grafana by now and not using graphite dashboards.

You're right, running collectstatic creates that missing folder. I was running all side of the doc ... but didn't see that one ...

I was talking of the lines 79 and 257 in that same file.
