Getting edx devstack to run on Windows

1) Fix issue https://github.com/edx/edx-platform/issues/3230

2) Change Vagrant ansible-play command to

ansible-playbook -i localhost, -c local vagrant-devstack.yml --tags=deploy -e configuration_version=master -e edx_ansible_source_repo=https://github.com/lsiu/configuration.git -e edx_platform_repo=https://github.com/lsiu/edx-platform.git -e edx_platform_version=master -vvv

3) Fix symbolic link issue
See: https://github.com/edx/configuration/wiki/Vagrant-troubleshooting#dealing-with-line-endings-and-symlinks-under-windows

 # You need to run this from cygwin, not the Windows command-line (see above)
 git rm --cached -r . && git reset --hard

 git config --global alias.rm-symlinks '!__git_rm_symlinks(){ for symlink in `git ls-files -s | grep -E "^120000" | cut -f2`; do git rm-symlink "$symlink"; git update-index --assume-unchanged "$symlink"; done; }; __git_rm_symlinks'
 git config --global alias.checkout-symlinks '!__git_checkout_symlinks(){ POS=$'\''/'\''; DOS=$'\''\\\\'\''; for symlink in `git ls-files -s | grep -E "^120000" | cut -f2`; do git update-index --no-assume-unchanged "$symlink"; if [ -d "$symlink" ]; then dossymlink=${symlink//$POS/$DOS}; cmd //C rmdir //S //Q "$dossymlink"; fi; git  checkout -- "$symlink"; echo "Restored git symlink $symlink <<===>> `cat $symlink`"; done; }; __git_checkout_symlinks'
 git rm-symlinks

4) Before running `vagrant provision`, comment out the checkout and clean resets (if left in playbook, it will resets the above fix)
