[qa] githooks can be used to check commit msg format

[RahulPalve]

Hey, we can use githooks to force commit msg format, so that commit is not done until its in correct specification/format.
I want to work on this, can we discuss about this.

githook will look like this in our case:
.githooks/.commit-msg

if [[ $commit_msg =~ ^\[(feature|file|module)\].*#[0-9]+; then
    exit 0
else
    echo "$error_msg"
    exit 1
fi

We can do this with all other modules, Please share your thoughts

@RahulPalve We already have this in openwisp-utils. Now we only want to add this in the documentation so that everyone starts using it. We already have an issue for it and contributions are welcome for that (openwisp/openwisp-docs#100).
