Add a script for configuring adb for working remotely.

tools/android/adb_remote_setup.sh

+#!/bin/bash
+
+if [[ $# -ne 2 ]]; then
+  cat <<'EOF'
+Usage: adb_remote_setup.sh REMOTE_HOST REMOTE_ADB
+
+Configures adb on a remote machine to communicate with a device attached to the
+local machine. This is useful for installing APKs, running tests, etc while
+working remotely.
+
+Arguments:
+  REMOTE_HOST  hostname of remote machine
+  REMOTE_ADB   path to adb on the remote machine
+EOF
+  exit 1
+fi
+
+remote_host="$1"
+remote_adb="$2"
+
+if which kinit >/dev/null; then
+  # Allow ssh to succeed without typing your password multiple times.
+  kinit -R || kinit
+fi
+
+# Kill the adb server on the remote host.
+ssh "$remote_host" "$remote_adb kill-server"
+
+# Start the adb server locally.
+adb start-server
+
+# Forward various ports from the remote host to the local host:
+#   5037: adb

Could you read these ports out from build/android/pylib/constants.py instead?
Maybe even keep the list up to date there?

Maybe it would be easier to write this in python then? Or at least provide some
help for doing that which does not include grepping or ugly bash-trickses to
parse the .py file? Maybe create a helper function in constants.py you could
call from here?

+    -L 9031:localhost:9031 \
+    -R 10000:localhost:10000 \
+    -R 10201:localhost:10201 \
+    "$remote_host"
