Bug Description

Binary package hint: euca2ools

euca2ools currently reads its configuration from 1 of 2 places:
a.) environment variables
b.) command line arguments

the configuration above that is read includes:

In addition to being a non-typical way of specifying configuration, the
environment variables
contain sensitive information. It is generally considered less than secure to
set sensitive information in the environment.

Instead or in addition to (really only for backwards compat) euca2ools should
read configuration from a config file. I suggest:


And additionally allow the caller to specify a config file. Ie:

euca-run-instances --config /tmp/my-config eki-abcdefg

Order of preference is user supplied config file (--config) followed by $HOME/.eucarc followed by /etc/euca2ools/eucarc followed by the environment.

I'd also like to request the following:
 if no --config argument is found, and EUCA2OOLS_CFG is set (or some other environment variable) then it expected to have a path to a config file. ie:

# read default config
unset EUCA2OOLS_CFG; euca-describe-instances

# read /tmp/my.env.eucarc
export EUCA2OOLS_CFG=/tmp/my.env.eucarc; euca-describe-instances

# read /tmp/my.cmdline.cfg
unset EUCA2OOLS_CFG; euca-describe-instances --config /tmp/my.cmdline.cfg

# read /tmp/my.cmdline.cfg
export EUCA2OOLS_CFG=/tmp/my.env.eucarc; euca-describe-instances --config /tmp/my.cmdline.cfg

The benefit of this is that tools that invoke the euca2ools can be blissfully ignorant of --config, rather than having to explicitly support it.
