commit b824438e1c6a203f7175705161852928d4315329

    Move `iserv` into `utils` and change package name from `iserv-bin` to `iserv`
    
    Summary:
    This is done for consistency. We usually call the package file the same name the
    folder has.  The move into `utils` is done so that we can move the library into
    `libraries/iserv` and the proxy into `utils/iserv-proxy` and then break the
    `iserv.cabal` apart.  This will make building the cross compiler with TH
    simpler, because we can build the library and proxy as separate packages.
