Without this, «ec2: state=stopped instance_ids=…» would fail with a
traceback like this:
if inst.get_attribute('sourceDestCheck')['sourceDestCheck'] != source_dest_check:
NameError: global name 'source_dest_check' is not defined
Detached head detection seems to have broken somewhere a long the way
because git decided to change how that situation looks when doing a 'git
branch -a' which is performed by get_branches().
This is how git 1.7.1 displays this situation (which works):
shell> git branch -a
* (no branch)
master
This is the output from git 1.8.3.1 (which does not work):
shell> git branch -a
* (detached from e132711)
master
It looks like this same wording is used in the most recent version of
git (2.6.1 as of writing this).
Both `source_dest_check` and `termination_protection` variables are not
available within the scope of the startstopec2 instance method. This just
pulls them from module.params.
With shade > 0.13.0, networks can be created that are externally
accessible. This adds a parameter for that.
Also, add RETURN documentation and 'if __name__' check around call
to main().
I think in this commit 720aeffca2bd2ae1eca158abc2d1463a8597afb6
There was bug introduced where the ElastiCacheManager init method has
a number of positional arguments like so.
```py
def __init__(self, module, name, engine, cache_engine_version, node_type,
num_nodes, cache_port, parameter_group, cache_subnet_group,
cache_security_groups, security_group_ids, zone, wait,
hard_modify, region, **aws_connect_kwargs):
```
But then later in the code the positional arguments are passed in
like this.
```py
elasticache_manager = ElastiCacheManager(module, name, engine,
cache_engine_version, node_type,
num_nodes, cache_port,
cache_subnet_group,
cache_security_groups,
security_group_ids, parameter_group, zone, wait,
hard_modify, region, **aws_connect_kwargs)
```
If you count, you can see that cache_subnet_group, is being passed in
where the manager expects to see parameter_group.
