Support for ios_config + src + match: exact

[steffenschumacher]

SUMMARY

In order to keep a series of eg. class-maps and policy-maps in sync with a template/config file, it would be awesome if ios_config would be able to accept src config file and match == exact, so that Ansible would automatically remove stuff from policies beyond just ensuring presence of the lines in the src config.
This would apply generically to all indented segments of the config, such as zone based firewall, interface templates etc etc.

ISSUE TYPE

• Feature Idea

COMPONENT NAME

ios_config

ADDITIONAL INFORMATION

ios_config can ensure the lines from my template is present, but it could also ensure leftovers are removed within indented config blocks - it cannot (of course) remove entire config blocks which are removed from templates naturally.
The alternative to this, would be to do per-config-block tasks with individual parent/lines, and if I prefer to have eg. all my base QoS config bits in a single j2 template, then it gets hard to manage.
It would also allow me to reuse templates with eg. DNA Center, so they are in sync across all tools managing config
