Verified steps:

Configure "inventory.cfg"
Create new repo xwbj/backend_test_1 on github
Run xcat-inventory init, got error

Qustions:

Need to create working_dir folder manually?

Failed to run git pull in code, no branch at that time. So need to create master branch manually?

xcat-inventory commit

xcat-inventory push ---- will be merged into master? If not, when checkout to mater will get error.

# xcat-inventory checkout master
checked out to revision master

xcat-inventory pull
xcat-inventory workspace-new/list/delete/checkout

Whether need to config user.name and user.email?
