Bug Description

Support for allocation unit was added via bug 1589588. An alloc-unit
field has been added to IpamSubnetType. The default value is 1.

Agent should advertise an IP prefix based on the alloc-unit value.
For example if an instance-ip has address 10.1.1.17 and alloc-unit
is 16, a route needs to be advertised for 10.1.1.16/28.

This should be supported for both inet and inet6 addresses.
It should also work in conjunction with the flat-subnet feature (see
bug 1592970).

Advertise Instance-ip with prefix using alloc-unit

Issue: There is a requirement of assigning alloc-block(power of 2)
vm instance-ip. Today we are creating UC routes for instance-ip
with /32 prefix. Now we need to create and advertise routes
for instance-ip with prefix calculated based on alloc-unit present
in IPAM configuration.
Fix: Store alloc-unit configuration in VnIpam structure and use
it while VM Interface is being created. Add UC route accordingly
and RouteExport will automatically exports the route.

Fix UT.

Following commit modified installation of vm interface route. It is being
installed when IPAM is present. Test case had a test to check for evpn route and
inet route in absence of Ipam. That fails because of this commit. Fixing the
same.
