Any implications to having a static cache initialized and unused if an
alternate cache is passed in via the other constructors?
> StellarProcessor should have a static expression cache

> Project: Metron
> Issue Type: Bug
> Reporter: Casey Stella

> We recreate StellarProcessor objects all over the place which do not reuse
> their expression caches. This results in a significant performance
> regression as we are compiling the expression and then processing for every
> message, rather than compiling once and reusing.
