Increase timeout in tests

[devdattakulkarni]

We have defined a timeout of 30 seconds for creating the CRD defined in ResourceComposition.
https://github.com/cloud-ark/kubeplus/blob/master/tests/tests.py#L92

Sometime it can take more than that for CRD registration to complete.
It will be good to increase this timeout value.
