Give integer maas constraints without decimal

Give integer maas constraints without decimal

Currently generic cpu and mem constraints are cast to float inside
juju, this isn't really useful for memory in MB or cpu count as used
by MaaS. It also happens to upset the current code. Giving the
integer form instead is reasonable.

Please take a look.

lgtm, fwiw, the float usage is based on some of the cloud providers using them
for instance type sizing for cpu. the conversion at usage/provider interaction
time here looks good.
