Make the max host default 100. We are seeing with moderate number of hosts i.e. 500 hosts having a few host variable each runs into max size of nginx message and nginx rejects the request.
we are therefor keeping the value small so that it doesn't fail with decent number of host variables as well.
remove the 999 hosts test because the default max is 100
fix the credential check
fix the instance groups and execution env permission checks
