Summary: Allow ssh keypairs to be created if developer flag set and user ! cloud

Detail: Previously in the code we allowed the configuration to create ssh
keypairs and put them in the configuration table so that systemvms could have
ssh key auth and work properly if the user was 'cloud' or if the developer
configuration item was set to true. It got changed to requiring both the cloud
user and the developer flag (using an || on a negative) somwhere along the way.
This changes it back to && on a negative to allow us to run as non-cloud users
with the dev flag set, and for cloud to deploy properly without the developer
flag.
