pushkey: expose "publicphases" namespace

In order to improve the discovery mechanism for phases for mega-headed
repositories, we wish to expose public phase heads as opposed to draft
phase roots.

We enable this by introducing a new "publicphases" namespace.

We can't easily re-use the "phases" namespace because the "listkeys"
wire protocol command doesn't currently take any arguments (other than
the phase name) and introducing an argument that is unique to a single
namespace feels wrong.

The new namespace is read only.
