Add SROS multiline show port support

[mjbear]

resolves #2301

• Add support for multiline show port lines
• As a side-effect of regenerating the test data, keys in the YAML are in alphabetical order
• Simplify states (since Port state could be collapsed into the Start state)

Example:

esat-11/1/c65 Up         Link Up                          conn   100GBASE-LR4*
esat-11/1/c65/u1
              Up    Yes  Up      9212 9212    - accs dotq cgige  

Notes:

• We could move the two new patterns below the = sign separator pattern instead of negating the presence of an equal sign in PORT_ID. The equal sign negation will continue to function even if pattern lines are moved around in future template edits, so the negation pattern is probably most ideal.
