gnocchi is strongly typed when compared to classical ceilometer db where 
you can dump anything and everything. we don't support wildcards as is 
but i believe it's something we can aim to support?

Mehdi is currently in process of implementing dynamic resources which 
would give more flexiblity on what type of data we can store in Gnocchi. 
i believe from ceilometer pov, we can add support to allow wildcard 
support in regards to adding new metrics.
