Code Issues Proposed changes

enable multiple collector workers

Browse Source 
currently, a single worker thread writes received samples into
database. this is fine for most occasions but during message
spikes, it is not enough. this patch increase amount of workers to
half the number of processors (so we can ensure ceilometer maintains
lightweight design)

this will also help validate mulitple worker setup works.
