gordon chung 80786e0d23 enable multiple collector workers
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.

# lib/ceilometer
# Install and start **Ceilometer** service
# To enable a minimal set of Ceilometer services, add the following to localrc:
#
# enable_service ceilometer-acompute ceilometer-acentral ceilometer-anotification ceilometer-collector ceilometer-api
#
# To ensure Ceilometer alarming services are enabled also, further add to the localrc:
#
# enable_service ceilometer-alarm-notifier ceilometer-alarm-evaluator
# Dependencies:
#
# - functions
# - OS_AUTH_URL for auth in api
# - DEST set to the destination directory
# - SERVICE_PASSWORD, SERVICE_TENANT_NAME for auth in api
# - STACK_USER service user
# stack.sh
# ---------
# - install_ceilometer
# - configure_ceilometer
# - init_ceilometer
# - start_ceilometer
# - stop_ceilometer
# - cleanup_ceilometer
