packages provider inconsistent results

[glensc]

Description

i find debian packages listing inconsistent with one that rpm provides.

• rpm system has "release" portion
• deb system "release" is included in "version" portion
• some deb package names contain archtecture zlib1g:amd64
• debian versions also include "epoch"

ideally i'd see:

• rpm systems include extra arch tag
• deb systems include arch tag, extract it from name if needed
• deb systems include release tag
• epoch moved to extra tag
• installdate missing for both systems, add it

examples from systems

rpm system:

# knife node show fqdn -a packages
pld:
  packages:
    glibc-misc:
      release: 21
      version: 2.3.6
    glibc64:
      release: 21
      version: 2.3.6

debian-7 system:

# knife node show fqdn -a packages
debian:
  packages:
    acpi:
      version: 1.6-1
    zlib1g:amd64:
      version: 1:1.2.7.dfsg-13

Ohai Version

Ohai: 7.4.0, but packages is taken from ohai that was merged in v8.9.0 lib/ohai/plugins/packages.rb

Platform Version

Debian 7

#820 was merged adding:

• rpm: add epoch, arch
• deb: add arch
• deb: fix arch being part of the name attribute

however, there's still todo:

• deb: explode version to components (epoch, version, release), see questions in #820
• deb: add installdate attribute
