Query options for requesting a relay

[nskinkel]

What parameters do we need to be able to query to get router information? What I currently have:

• flags
• address (can exit to)
• port (can exit to)

Options we still need:

• or_port (router that uses this as its or_port)
• dir_port (router that uses this as its dir_port)
• not_asn (router that is not in a given ASN)

Options we may need:

• not_cc (router that is not in this country code)

Please add anything other parameters we'll need to query by.

Closed. Implemented most of this and leaving the remaining query options as separate, individual issues.
