A Lua sandbox raises an exception when it tries to inject a message
larger than the configured output_limit value (default: 63KiB). The
same applies to the cjson library when trying to encode a Lua structure
resulting in a string larger than the same limit.
This change adds safe_* versions of the inject_message(),
inject_payload() and cjson.encode() functions. It also modifies the
existing Lua plugins to use the safe versions instead.

RabbitMQ logs aren't following good logging guidelines and in
particular, the severity level isn't always mapping the Syslog levels.
This change updates the Lua decoder to cope with these logs.

This is an import of the initial LMA PoC code. For now, it only covers
the collection of logs (notifications will be added in a subsequent
commit).
There's been a bit of rewrite to:
- decouple the Heka configuration from the LMA collector.
- run the Heka service as non-root when possible (Ubuntu only for now
due to file permission issues on CentOS [1]).
- adapt to version 0.9 of Heka.
