Fixes #7170

At the point the exception is handled, it is likely due to error loading
a sub-template included from main template. Besides file not found, it
can be caused also by include path failing Jinja2 checks. Now, when
rendering the exception from Jinja, it will include exception name. This
will give basic context or *what* the error is.

Fix missing arg for _remote_chmod method.

Default is set to 300 seconds, which is AWS default.

This PR fixes a bug (#7898) where instances created within an autoscaling group using the `ec2_asg` module gets immediately terminated because the `health_check_period` is set to 0, which causes the instance to be checked without having the time to actually boot.

Adding `health_check_type` is needed because you may want to check your instance health against an ELB instead of just EC2 default cloudwatch.

AWS allows to define launch configuration with spot instances. This is also natively supported by boto (see http://boto.readthedocs.org/en/latest/ref/autoscale.html)
