clone_customer_repository: re-initailize repository after cloning. Copy

.githhoks/post-merge hook into .git/hooks/. post-merge will list the
names of changed files and write them to /tmp/git-pull.
The existence of /tmp/git-pull shows that there have been received changed files.

# At this point, you've told the remote what you want.

# You receive the pack (set of compressed objects) and unpack it.

# You've fetched the branch 'master' from the given remote;

#
# Git notes the original position of your master branch (9d447d2)
# and the new position (f74fb21) it's been fast-forwarded to.
# If you had diverged from the remote's master branch,
# you'd see the output of a recursive merge here - Merge made
# by recursive, possibly along with some Auto-merged <file>
# and (oh no!) merge conflicts!
