Support export / list intents by client

[orishoshan]

Today, the otterize network-mapper export and otterize network-mapper list only support export by server and by namespace.

There is currently no way to export intents for a single client, which you may be trying to do if you own that service.

Proposal: add --client flag to the two commands, that behaves like --server, except filtering the intents that are outputted by client.
