METRON-434: JSON Parser
There are some situations where your data is already in JSON form and
parsing should be as simple as passing the data through, adding `timestamp` and
`original_message` along the way. This JIRA will create a parser which will
take a JSON map in.
Since we have standardized on one-dimensional maps, we must handle data
which contains inner maps. Inner maps should be handled pluggably by doing one
of the following (configurably):
* doing nothing
* unfolding maps (e.g. `{ "foo" : { "bar" : 7 } }` is transformed into
`{"foo.bar" : 7 }`)
* throwing an exception
* dropping the inner map

Could strings instead reference the enums directly? e.g.
MapStrategy.ALLOW.name()
