MultiReaderMemcache

Read from multiple clients in round-robin fashion, "grabby hands" style using Kestrel's memcache protocol. The load balancing is simple, and falls out naturally from the user of the {{Offer}} mechanism: When there are multiple available messages, round-robin across them. Otherwise, wait for the first message to arrive.

Example with a custom client builder:

val readHandle =
  MultiReaderMemcache("/the/path", "the-queue")
    .clientBuilder(
      ClientBuilder()
        .codec(MultiReaderMemcache.codec)
        .requestTimeout(1.minute)
        .connectTimeout(1.minute)
        .hostConnectionLimit(1) /* etc... but do not set hosts or build */)
    .retryBackoffs(/* Stream[Duration], Timer; optional */)
    .build()

Create a new MultiReader which dispatches requests to dest using the memcache protocol.
Create a new MultiReader which dispatches requests to dest using the memcache protocol.
dest
the name of the destination which requests are dispatched to. See Names for more detail.
queueName
the name of the queue to read from TODO: dest is eagerly resolved at client creation time, so name resolution does not behave dynamically with respect to local dtabs (unlike com.twitter.finagle.factory.BindingFactory. In practice this is not a problem since ReadHandle is not on the request path. Weights are discarded.
