Enforce flake8 E123/6/7/8 in ironic

This patch enforces the rules E123, E126, E127, and E128 in the ironic
code base:

E123 - closing bracket does not match indentation of opening
bracket’s line
E126 - continuation line over-indented for hanging indent
E127 - continuation line over-indented for visual indent
E128 - continuation line under-indented for visual indent

This fixes any parts of the current code which fails these rules and
removes these rules from the tox.ini flake8 ignore list.
