Pavel Bondar 625de54de3 Switch to pluggable IPAM implementation
This patch does unconditional switch from non-pluggable IPAM to
pluggable IPAM for all deployments during upgrade to Neutron.

Pluggable IPAM is enabled by pointing ipam_driver default to reference
driver. User who manually set ipam_driver in neutron.conf will continue
to use ipam_driver of their choice.

During upgrade data is migrated from non-pluggable IPAM tables to
pluggable IPAM tables using alembic_migration. Availability ranges
(IPAvailabilityRange) is no longer used to calculate next available ip
address, so migration for this table is not included.

Migration is covered with functional tests. Dataset with subnets,
allocation pools and ip allocations is loaded prior to migration.
Once migration is completed ipam related tables are checked
if data is migrated properly.

Built-in IPAM implementation becomes obsolete and is planned to be
removed in upcoming commits.
