Increment default install version to 0.8 -- and test.

Add a way for this cookbook to update a version of heka on an already existing deploy.

The version can be obtained via a package manager, or via "hekad -version" and then compared to what is in default['heka']['download']['version'] -- if the version installed is older than the one specified in the cookbook, then we should download and update heka.

Initial load of cookbook fails, subsequent runs succeed.

It would be cool to add some travis tests.

Will require using the RPM to install heka.

The error

resource file[/etc/consul.d/service-consul.json] is configured to notify resource service[consul] with action reload, but service[consul] cannot be found in the resource collection. file[/etc/consul.d/service-consul.json] is defined in /var/chef/cache/cookbooks/consul/providers/service_def.rb:27:in `block (2 levels) in class_from_file'

My code:

node['sensiolabs_consul']['services'].each do |name, definition|
    consul_service_def name do
        id definition['id'] unless definition['id'].nil?
        port definition['port'] unless definition['port'].nil?
        tags definition['tags'] unless definition['tags'].nil?
        check definition['check'] unless definition['check'].nil?
    end
end

I used init for service configuration

Heka 0.5.2 is out:

https://github.com/mozilla-services/heka/blob/v0.5.2/CHANGES.txt

Update the cookbook to install the new version.

Add a conditional to check if Heka is already installed, and don't download the package if it is.
