Problems starting TSS in ElasTest HEK

[EduJGURJC]

Hi,

we are having problems starting Test Support Services in ElasTest HEK.

The problem occurs when the ESM checks whether the namespace exists or not before creating it (https://github.com/elastest/elastest-service-manager/blob/master/src/adapters/resources.py#L686). The Kubernetes api returns a 404 not found, and the ESM code throws an exception:
