MEDIUM: ssl: revert ssl/tls version settings relative to default-server.

MEDIUM: ssl: revert ssl/tls version settings relative to default-server.

Plan is to add min-tlsxx max-tlsxx configuration, more consistent than no-tlsxx.
min-tlsxx and max-tlsxx can be overwrite on local definition. This directives
should be the only ones needed in default-server.
To simplify next patches (rework of tls versions settings with min/max) all
ssl/tls version settings relative to default-server are reverted first:
remove: 'sslv3', 'tls*', 'no-force-sslv3', 'no-force-tls*'.
remove from default-server: 'no-sslv3', 'no-tls*'.
Note:
. force-tlsxx == min-tlsxx + max-tlsxx : would be ok in default-server.
. no-tlsxx is keep for compatibility: should not be propagated to default-server.
