Fix deploy for deprecated api versions

[seleznev]

Deprecation checker currently silently blocks provisioning because of wrong placed DeprecationError exception handler:

k8s-handle/k8s_handle/__init__.py

Lines 233 to 234 in 678304c

	except DeprecationError as e:
	log.warning('Deprecation warning: {}'.format(e))

But it should be handled somewhere around:

k8s-handle/k8s_handle/__init__.py

Lines 115 to 116 in 678304c

	except client.api_client.ApiException:
	log.warning("Error while getting API version, deprecation check will be skipped.")

).

So, I suggest to remove exception completely.

LGTM.

It would be good to check if _is_deprecated is still used somewhere, btw.
