There is no call to yum_base using 'cachedir' argument, so
while it work fine from a cursory look, that's useless code,
and so should be removed to clarify the code.
Using the rpm module prevent a uneeded fork, and permit
to skip the signature checking which slow down a bit the
operation, and which would be done by yum on installation
anyway.
Removes default value from ec2_lc so it can create launch configurations valid on a EC2-Classic environment. AWS API will not accept a assign_public_ip when creating an ASG outside of VPC.
boto can throw SSLError when timeouts occur (among other SSL errors). Catch these so proper JSON can be returned, and also add the ability to retry the operation.
There's an open issue in boto for this: https://github.com/boto/boto/issues/2409
Here's a sample stacktrace that inspired me to work on this. I'm on 1.7, but there's no meaningful differences in the 1.8 release that would affect this. I've added line breaks to the trace for readability.
