When a node is marked as online (“gnt-node modify -O no …”), an RPC is
made to the node to check whether the node daemon is running. My recent
RPC changes led to offline nodes being ignored before the actual call is
made, thereby causing this check to fail. This is a workaround and needs
to be cleaned up later.

These two calls, “upload_file” and “write_ssconf_files” are treated
separated as they're used by the configuration, where we can't use the
normal resolver.

There's still some duplicated code in rpc.py, but that will be taken
care of in future patches.

With these changes job queue RPC will finally show up on the lock
monitor. See below for an example. A job queue-specific class is used to
restrict the use of a static list for name resolution to the job queue.
Further improvements can be made to not re-create the whole RPC client
for every call (e.g. by using a more dynamic resolver), but for now this
works.

We don't re-use cURL objects anymore, so there's no need to reset them.
PycURL 7.19.0 has a reference counting bug leading to a crash after
a certain number of performed requests.

Since a unittest depended on this function for a test, it is replaced
with a per-request completion callback, which could also be used by
users of the HTTP client.

Unittests are updated and a test for the request object's “nice name”,
used by the lock monitor, is included.
