[NET] Refactor TLS configuration.

Browse Source 
Use a TLSOptions configuration object which is created via static
functions.

- "TLSOptions.client": uses the standard CA and common name verification.
- "TLSOptions.client_unsafe": uses optional CA verification (i.e. if specified)
- "TLSOptions.server": is the standard server configuration (chain + key)

This will allow us to expand the TLS configuration options to include
e.g. mutual authentication without bloating the classes that uses
StreamPeerTLS and PacketPeerDTLS as underlying peers.

Connects a [param packet_peer] beginning the DTLS handshake using the underlying [PacketPeerUDP] which must be connected (see [method PacketPeerUDP.connect_to_host]). If [param validate_certs] is [code]true[/code], [PacketPeerDTLS] will validate that the certificate presented by the remote peer and match it with the [param for_hostname] argument. You can specify a custom [X509Certificate] to use for validation via the [param valid_certificate] argument.
Connects a [param packet_peer] beginning the DTLS handshake using the underlying [PacketPeerUDP] which must be connected (see [method PacketPeerUDP.connect_to_host]). You can optionally specify the [param client_options] to be used while verifying the TLS connections. See [method TLSOptions.client] and [method TLSOptions.client_unsafe].
