Allocate buffer large enough to hold a UDP packet of maximum size

This change was originally introduced by @pablosichert in DataDog#140 but was
superseded by DataDog#148. His orginal comment:

> I thought it would make sense to either be deliberate about dropping the
> contents entirely (buffer size of 0) or allocate enough to fit a UDP packet of
> max size.

Closes DataDog#140

Convert lading configuration from toml to yaml, remove rayon

This commit makes a breaking change to lading and opens up the 0.6 release
series. The major change here is the conversion to the use of yaml in lading's
configuration file, driven by the toml crates inability to deal with
deserializing enums that have values in them. This means our 'static' format
variant is not actually usable in toml-land, as that variant embeds a path in
it.

I have also taken the opportunity to do a little house cleaning, removing the
rayon dependency from file_gen and adjusting the goofy case issues that we've
had in configuration for a minute. Now every option will be snake_case and users
don't have to deal with the odd Post etc anymore.

Configure all lading programs through files (DataDog#99)

Previously we allowed for some lading programs to be configured through
command-line flags. This makes lading challenging to use in contexts where
file-based configuration is more convenient, so we now have every lading binary
read a config file from under `/etc/lading`.

Reduce the size of splunk hec payloads

The previous setup made truly massive payloads, larger than were necessary. This
implies the project needs a "bounded string" type, or a rethink of how AsciiStr
works.

* Add splunk_hec payload

This commit adds the ability to generate splunk's hec payload format. Time
doesn't vary presently, which is a little weird, but that seems like it's easy
to resolve if we ever need.
