Apply black to dae and network directory py files

[mrmundt]

Fixes (Partly) #329

Summary/Motivation:

This is the first in a relatively long string of PRs to apply PEP8 standards via black to Pyomo. We are following the standard used by IDAES except that we are adding the -S option: Don't normalize string quotes or prefixes and the -C option: Don't use trailing commas as a reason to split lines.

NOTE: All changes are NFC.

Full command used: black -S -C pyomo/dae && black -S -C pyomo/network

⚠️ Please squash this at merge. ⚠️

Changes proposed in this PR:

• Apply black to the dae and network directory py files
• Manually fix instances where two lines were merged and left " " or ' '

Everything looks OK. I found (and fixed) a couple mangled comments.
