powerman 2.30.20 (new formula)

powerman is a set of tools for inspecting and controlling PDUs
(power distribution units) over HTTP, SNMP and serial lines.
nut 2.7.2 (new formula)

nut, also known as network UPS tools, is a set of tools for
communicating with UPSes, PDUs and solar power controllers. It provides
a daemon, logging and drivers. It communicated over serial lines, USB,
SNMP, IPMI and via HTTP. The name 'nut' is not particularly descriptive
and does not help users find UPS tools, but it matches the Debian
package nomenclature.

This pull request requires the 'powerline' new formula pull request.
