Treat 'comment' as multiline

[PieterL75]

SUMMARY

Adding a comment is done by either prefixing it with !! or send it as 'comment' config.
Both options are not possible with the current cliconfig.

ISSUE TYPE

• !! cannot be used, as all line starting with ! are stripped
• comment cannot be used, as it is multiline command (like a banner)

ADDITIONAL INFORMATION

AVD 5.2.2 allows to add comments to interfaces. These are generated as a !! comment on the interface configuration.
When deployed via CV, it works fine, but when using eAPI, the comments are not send to the device

The solution is to either allow lines prefixed by !!, or treat 'comment' as a multiline
