Allow netutils to handle multiple consecutive banners.

[swanandtambe]

Environment

• netutils version: 1.17.3

Proposed Functionality

Allow netutils to handle multiple consecutive banners.

Use Case

Cisco IOS supports many (7) banners. Configs with more banners will fail config compliance with the error “RENDER COMPLIANCE TASK GROUP failed: Unable to parse banner end.” This happens even if the compliance rule is specific to the banner like “banner login ^C”

Sample config

banner exec ^C
