Munin contributed plugins

Lots of changes:

• Fix the README
• Add a makefile to fetch bootstrap, lazyload, jquery, the munin logo, and the munin favicon
• Mostly re-write dynazoom. It works very much like the stock one now, with a few extra quick buttons, and of course the bootstrap styling...

relayd: avoid matching table defs within comments

if a table is commented out, you currently get an entry for the hosts
that the entry contains but you'll get NaN for those hosts all the time
if they are not defined elsewhere.

to avoid that we anchor our match to the beginning of lines and permit...

puppetdb: implement cert validation and client cert auth

It is very common for PuppetDB installs to run on a different host than
the puppetmaster. In such cases, a certificate file is normally used to
establish an encrypted communication to the server.

The most common setup for this server certificate is to use a...

Remove obsolete bebox plugins

The plugins beboxsync, beboxstats and beboxstats.expect are obsolete.

[network/hostsdeny] Refactor to support any blocked service

The HostDenied field is renamed to ssh. To preserve existing data,

1. cd /var/lib/munin/example.net

This refactor incidentally also fixes a bug where empty or commented-out...

[isp/internode] Cache initial API response

The API tends to be unstable and often fail with a 500,

[isp/internode] Fix (some) issues with DIRTYCONFIG

We need to set the date for all plugins, otherwise the lagging `daily`
one is assumed for all, and confuses spoolfetch and other time-based
sanity checks.

[isp/internode_usage] Code cleanup

Also make the daily graph more flexible, by always reporting the second
last value (presumably the previous, but sometimes the API lags a bit,
and actively requesting by date result in never reporting some late
data).
