[kudu-CR] rpc: call-level feature flags

["Dan Burkert (Code Review)" <ge...@cloudera.org>]

Hello Kudu Jenkins,

I'd like you to reexamine a change.  Please visit

    http://gerrit.cloudera.org:8080/2239

to look at the new patch set (#2).

Change subject: rpc: call-level feature flags
......................................................................

rpc: call-level feature flags

This adds a new API RpcController::RequireServerFeature on the client side, and
ServiceIf::SupportsFeature on the service side. These APIs make it possible for
the client to require application-specific feature support on the server in
order for an individual RPC call to be serviced. If the feature is not
supported, the RPC is rejected and an appropriate error is returned.

This will be used in the future when adding features to existing RPC messages,
so that the server does not silently ignore additional fields.

These RPC features require a new RPC feature flag, APPLICATION_FEATURE_FLAGS, to
be supported. If the server does not support that RPC feature flag, then the
call will fail on the client side.
