remote_prefix is always logged empty. when there is no value then field name can be avoided as this is optional field.

"is_si = 0 remote_prefix = vrouter_ip = 10.204.217.102"

Fix VM name not getting exported in Session records.

For server sessions, VM name should be picked from reverse-flow instead of
forward.
Also fixed the following issues
1. Remote-prefix showing empty string when data is not available.
(Fix is to not export the field itself when data is not available)
2. Agent introspect showing remote-tagset for local-tagset field
