Dealing with Alcor Submodule

ACA relies on the protobuf schema located under Alcor repro, therefore, it has a submodule to Alcor to use it.

ericli@Erics-MacBook-Pro aca-dev % git status
On branch perf/hashtable
Your branch is up to date with 'origin/perf/hashtable'.

nothing to commit, working tree clean
ericli@Erics-MacBook-Pro aca-dev % ls
CMakeCache.txt		LICENSE			SCHEDULE.md		cmake_install.cmake	include

Noticed git status shows a clean state and the alcor directory under aca.

In the event that a user move the Alcor submodule in the local branch unintentionally (that could happen when switching a development branch which points to a different Alcor submodule):

ericli@Erics-MacBook-Pro aca-dev % cd alcor
ericli@Erics-MacBook-Pro alcor % git checkout master
Switched to branch 'master'

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

	modified:   alcor (new commits)

no changes added to commit (use "git add" and/or "git commit -a")
ericli@Erics-MacBook-Pro aca-dev %

try to do the below to see if that fixes it:

ericli@Erics-MacBook-Pro aca-dev % git submodule update --init --recursive

You can also move Alcor submodule back to the offical master’s location seen at: https://github.com/futurewei-cloud/alcor-control-agent (e.g. alcor @ 2d1490d)

ericli@Erics-MacBook-Pro aca-dev % cd alcor
ericli@Erics-MacBook-Pro alcor % git checkout 2d1490d
Note: checking out '2d1490d'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 2d1490d [Contract] Update Contract for DNS/Router, Resolve Discrepancy (#484)
