define empty request_key method for sumstats in cluster mode.

This prevents the worker nodes from crashing, when request_key is used
in cluster mode and called on the worker and the manager nodes (i.e. when
a non-cluster-aware script is used).

Addresses BIT-1177
Add a new section "Cluster Configuration" to the docs

Added a new section that is intended as a how-to for configuring a Bro
cluster (this section does not discuss cluster architecture or theory)
that is aimed at beginners to Bro.  Most of this content was moved here
from the BroControl doc (which is now intended as more of a reference guide
for more experienced users) and the load balancing FAQ on the website.

Let TLS analyzer fail better when no longer in sync with the data stream. The
version field in each record-layer packet is now re-checked.
Add new features from other branch to the heartbleed-detector (and clean them up).

We should now quite reliably detect scans/attacks, even when encrypted and not succesful.
move tls content types from heartbleed to consts.bro. Seems better to put them there...
Replace errors when parsing x509 certs with weirds (as requested by Seth).

The one I did not replace is a malloc issue which I think really should
raise an error.
