storage policy schema problems

[baallan]

We have samplers (procstat, shm, filesingle, papi, probably others) all of which would be better off if they could create unique schema names (from some user-defined base name) and then have storage policies be defined on some regular expression instead of a string literal schema name (like 'meminfo').

In the case of shm_sampler, we need this to make the sampler usable in production-- the daemon administrator will never know what the application data naming is from the user.

strgp_add name=store_shm plugin=store_csv schema=shm_sampler_* container=node strgp_prdcr_add name=store_shm regex=.* strgp_start name=store_shm

What makes this impossible, or hard?

This is vaguely related to !45, !46.
