When calling the client identity renew API, it is possible the
target node ID is provided by either the URI or within the request
body. This change fixes a bug where all calls using a node_id query
parameter would be reject as it failed to decode the empty request
body.

The HTTP request body contains the node ID where the request should
be routed and without decoding this, we cannot route to anything
other than local nodes.
The Nomad clients store their Nomad identity in memory and within
their state store. While active, it is not possible to dump the
state to view the stored identity token, so having a way to view
the current claims while running aids debugging and operations.
This change adds a client identity workflow, allowing operators
to view the current claims of the nodes identity. It does not
return any of the signing key material.
