build: tools: add in roomservice

This is a new implementation of roomservice
use the new github search api to reduce the memory footprint, and make it less processor intensive
allow for unofficial devices to fetch dependencies. just specify your github organization

to fetch dependencies:
    add a file called 'omni.dependencies' to the root of your device tree
    an example configuration for the dependency file is:

[
  {
    "repository": "android_device_sony_common",
    "target_path": "device/sony/common"
  },
  {
    "repository": "legacybop/android_hardware_qcom_display-legacy",
    "target_path": "hardware/qcom/display-legacy",
    "revision": "omni-4.3"
  }

please note that comments can not go into this file. It must be valid json

PatchSet 7:
  add support to change port script to another team with config
  finished pep8'ing
  more checks on manifest parsing

This is required when device tree depends on dependencies to lunch.

roomservice: Fix handling of devices with _ in their name

Currently, roomservice takes every _ in the device tree name and
replaces it with /

Instead, strip the device name (such as pollux_windy) from the repo
name before replacing _ with / and then append it again when we're done
