Give option on how git tracks submodules.

Allows user to decide if git submodule should track branches/tags or track commit hashes defined in the superproject.

Add track_branches parameter to the git module.

Defaults to track branches behavior.
Chnge option name to track_submodule_branches.

Update documentation to reflect what the actual effect of the option.

ec2_snapshot: document wait, wait_timeout params

Document the wait and wait_timeout params for ec2_snapshot.

This is important because snapshots can take a long time to complete,
and the module defaults to wait=yes.
