Proper support for RHEL/CentOS 5 (the only thing it needs now is to call python26)

adding param to allow for specifying custom iops setting when creating an EBS volume
apt: Run remove commands noninteractively

I'm seeing ansible hang when trying to remove a package, and the hung
process is `whiptail` like in #2763. It looks like we only use
`APT_ENVVARS` and `DPKG_OPTIONS` for the `apt` commands in install()
and upgrade(). This change uses them in remove() as well, which fixes
the hang.
Add support for INI comments that begin with '#' or ';'

Ini file format does not have a standard but ';' is used more often than '#' for comments
Minor doc update to s3 & ec2 modules

Adds some additional docs about the module parameters for s3
and ec2 modules.
