Include user's command in smart server header

[Jonathan Lange]

There's no good way for a Bazaar host to log information about what its users think that they are doing.

One way to make this easier would be to send the command that the user supplied to bzr ('info', 'log' etc) in the smart server hello command, or something similar.

[Andrew Bennetts (spiv)]

The "hello" command is being phased out; recent clients shouldn't be using it much, if at all.

It might be reasonable to add a header like "CLI command": "push" to requests, though. (But I wouldn't want to send more detail than just the command name, and even then just command names from core and not plugins, to minimise chances of inadvertently leaking data that the client doesn't want to share.)

[John A Meinel (jameinel)]

We have '-Dhpss' on the server side now, though that logs the specific actions, and not the user requests. (So it says that they are fetching data, but not whether that is 'log' vs 'pull' vs 'branch'.
