Configurable introspection data storage backend [1] is
proposed to provide flexible extension of introspection
data storage instead of the single support of Swift storage
backend.
This patch adds database support for using ironic-inspector
database as the storage backend.
A table named ``introspection_data`` is created to serve as
the storage for introspected data.
