Kevin_Zheng e2e372b2b1 Allow run metadata api per cell

Adds configuration option ``[api]/local_metadata_per_cell``
to allow user run Nova metadata API service per cell. Doing
this can avoid query API DB for instance information each
time an instance query for its metadata.

Implements blueprint run-meta-api-per-cell

Description
