apply server side ssl profile per CLI

The client/server side of each profile is part of the profile type and so doesn't need to be assigned when applying to a Virtual Server but you can define the context following each profile.

For example:

tmsh modify ltm virtual example_443 profiles add { QA_serverside_SSL { context serverside } }

But you can simple add the Server SSL profile to your VS as you stated and it working:

tmsh modify ltm virtual example_443 profiles add {QA_serverside_SSL}
