Dtab

There are two headers used to control local Dtabs in linkerd:

l5d-ctx-dtab is read and _written_ by linkerd. It is intended to managed entirely by linkerd, and applications should only forward requests prefixed by l5d-ctx-*.

*NOTE*: the client module does not yet encode l5d-ctx-dtab. dtab-local is still to be relied on until https://github.com/twitter/finagle/pull/514 is complete.

2. l5d-dtab is to be provided by users. Applications are not required to forward l5d-dtab when fronted by linkerd.

l5d-dtab is appended to l5d-ctx-dtab, so that user-provided delegations take precdence.

class ClientFilter extends SimpleFilter[Request, Response]

Encodes the local dtab into the L5d-Ctx-Dtab header.
Encodes the local dtab into the L5d-Ctx-Dtab header.

To do
use DtabFilter.Extractor once it is released.
class ServerFilter extends SimpleFilter[Request, Response]

Extract a Dtab from the L5d-Ctx-Dtab and L5d-Dtab headers (in that order) and append them to the local context.
Extract a Dtab from the L5d-Ctx-Dtab and L5d-Dtab headers (in that order) and append them to the local context.
The L5d-Ctx-Dtab header is intended to be set by a linkerd instance, while the L5d-Dtab header is intended to be set by a user who wants to override delegation.

To do
use DtabFilter.Injector once it is released.
