Fix validation of ESXi network configuration

Currently, all validations fail because we cannot access the hosts with
secure connections. In #656 the
code has changed to take the configuration of the client connection from
the secret, however, the secret of the ESXi hosts is never set with the
insecure flag.

This change practically makes the client to the hosts be always
insecure. It's not that significant because the data we get from the
host does not include data that could be confidential.
