[strongSwan] left ID, right ID and no matching peer config

Hi Piyush,

If you set `rightcert` this will cause `rightid` to default to the
subject DN of the certificate, which in turn won't match "client".  So
either set `rightid=client` or don't set `leftid` on the client so the
client's own identity defaults to the subject DN of the certificate.
