delete stale file.  this is from when we used mysql to store tags
make Structured metrics usable without a config
remove the target yielding limit stuff, it was overkill
add tool to easily manually check proto1->proto2 upgrade for given metrics
ignore tags file
update todos
helpful debug info for SM list_metrics()
clean up empty n1,n2,... tags from catchall plugins
test for structured_metrics plugin loading
make catchall_statsd plugin better
add unit tests for catchall plugins
better way for catchall plugins to set n1, n2,.. tags

more elegant and more performant!
test for catchall_statsd count and rate
test native proto2 metrics
