Lee Yarwood 54edc7aeef tempest: Increase m1.nano and m1.micro RAM by 64MB to avoid tmpfs exhaustion ...

tmpfs exhaustion has long been suspected as the root issue behind
failures to load ssh keys and other metadata from local config drives as
documented in bug #1808010. This can also lead to failures fetching
metadata from n-metadata-api leaving Tempest unable to SSH into
instances.

This change increases the RAM of the m1.nano and m1.micro flavors by
64MB to hopefully avoid these errors going forward. This is also ahead
of our eventual upgrade to Cirros 0.5.0 where 128MB becomes a
requirement.
