There might be a performance impect of updating the metadata store on
bulk operations. Hence this flag which is disabling the collection by
default. If the queries to obtain the information are called with this
flag disabled, the database will throw an exception.
This PR introduces READ COMMITTED and READ UNCOMMITTED isolation levels.
The isolation level can be set with a config or with a query for different scopes.
Summary:
The configuration file that was used for the Debian/CentOS package was manually
written. This diff adds a configuration file generator that extracts all of the
necessary information about the flags directly from the built binary and uses
that information to generate the configuration file for the packages.
