Code review comment for lp:~pundiramit/linaro-android-build-tools/access_private_manifests

I did try to read userID from .bashrc/.profile/.gitconfig/bazaar.conf at first but the thing is that this userID is generated by linaro-private git administration and it may not be consistent with a user's existing usernames. At least in my case, the admin gave me an username "amitpundir" whereas my launchpad/git/gerrit/bzr ID is "pundiramit".

I can certainly rename ID to a much understandable LINARO_ANDROID_ACCESS_ID environmental variable.

I did not understand the last concern.
I'm initializing ID with "default-bot", which is a default unauthorised bot and do not have access to any private gits. I can very well leave ID uninitialized as well.
Once user provide correct access ID, I override "default-bot" with user provided ID and then replace "*-bot" e.g. "linaro-big-little-switcher-bot" with ID. I used "*-bot" because it could be any project specific bot. I'm counting on future default bots to be named on $PROJECT-bot as well.
