(PUP-3057) ensure acceptance tests run on sol10

* fixup solaris10 config file
* add forge_host to options file so tests can run outside rake
* confine IPS tests to solaris11
* skip zone tests as there is not enough drive space on our solaris10
    machines (QENG-1351)
* remove grep -q option for cross-platform sanity

This option is already set in the Rakefile, and is used for both git/package runs in jenkins, or when  using the rake tasks for manual testing.  The change Eric is making here, I believe, is to assist him in using the git/options.rb when running with beaker by hand, rather than through the rake tasks.  The downside is that it can now change in two places.  I think the issue Eric is having is that he runs acceptance a lot manually on vms he spins up with puppet installed from git, and he is used to using beaker directly, as he does for other projects, but needs the setup configuration in this file.  One thing I've suggested is a custom_options.rb that would pull in this config/git/options.rb, but then he needs this kind of customization always available.
