ec2_vol - add support for modifying existing volumes

[briantist]

SUMMARY

This is a re-submission of ansible/ansible#21588

A PR was opened to implement this but was ultimately closed without being merged seemingly due to disagreements over whether to require a complete port of the module to boto3:
ansible/ansible#22978

The need for the feature, particularly for expanding existing volumes, is still very real though.

Any update on this one or we just waiting 2.10 to be released?

@roy-boy As it stands the ec2_vol module is a boto (v2) based module and I believe the original boto python module doesn't support changing the size of volumes. While it's possible to create a hybrid boto/boto3 module (as done in ansible/ansible#22978) this generally results in a much higher risk of bugs creeping into the module as boto and boto3 have very different approaches to parameters, return values and exceptions.

There's a port of this module to boto3 in progress (#53). However, the bulk of contributors to both ansible.aws and community.aws are 'community' contributors and not directly paid to work on Ansible collections. As such, turn around can be much slower than people may like. Once #53 is merged reviving ansible/ansible#22978 should be relatively trivial.

@tremble , thanks for your reply, yeah understand the release cycle of open source project. No worries I can use python boto3 now as the workaround for my project and keep an eye on the 2.10 release notes. Cheers!
