Fix access_ip_v4/6 filters params for servers filter

While adding the json schema for servers filter query,
we added 'accessIPv4' and 'accessIPv6' as allowed params
but they do not match with what DB has. It is 'access_ip_v4'
and 'access_ip_v6' in DB.
This makes  'access_ip_v4' and 'access_ip_v6' filter stop working.

The schema should be fixed accordingly to allow the 'access_ip_v4'
and 'access_ip_v6' as valid filter.

'accessIPv4' and 'accessIPv6' are something the API accepts
and returns and internally API layer translate those param
to their respective field('access_ip_v4' and 'access_ip_v6')
present in DB.
So user does not know anything about 'access_ip_v4' and
'access_ip_v6'. They are not in API representation actually.

Later list filter and sort param should be same as field return
in GET or accepted in POST/PUT which are 'accessIPv4' and 'accessIPv6'.
But that is something new attribute support in filter and can be
done later after more discussion.
