FileBucket Files have been reimplemented as an indirector terminus so that
they can be transmitted over REST.
The old Network::Client.dipper has been replaced with a compatibility later
in FileBucket::Dipper that uses the indirector to access filebucket termini.

Slightly revised patch:
* No longer allows nil contents in FileBucket outside of initialization
* Uses File.exist? instead of the deprecated File.exists?
* Tweaks JSON serialization and de-serialization to include "path"

Deferred issues:
* Feature #3371 "FileBucket should not keep files in memory".
* Feature #3372 "Replace FileBucket Dipper with more idiomatic calls"

We just add a bit of information to the exception.

Made minor changes, including removing the parent class.

The functionality hasn't changed yet -- that comes in later patches --
but all but a couple of the older tests pass.

with 'yaml' still being the default but 'marshal' being an option.
This is because testing has shown drastic performance differences
between the two, with up to 70% of compile time being spent
in YAML code.  Use the 'catalog_format' setting to choose your format,
and the setting must be set on the client.

can reach the server.  It will still use the cached config if
there's a failure.
