fix(systemd): fix service detection

[ze42]

Fix service detection to properly ensure the service is running. Command also updated at other service.running/dead onlyif.

Fixes https://github.com/saltstack-formulas/mongodb-formula/issues/93 with the change suggested there

Not sure why Amazonlinux fails.

mmm... might be a bug in salt I've seen some time ago, and might still be there.

Enabling and launching at the same time fails. Splitting into 2 states (service.enabled and service.running) might do the trick.

HI, this PR is quite old now but I' interested in reviewing it to merge it if possible because I'm facing the same bug.

[daks]

I rebased this branch on master, added an Inspec test

diff --git a/test/integration/default/controls/archive_spec.rb b/test/integration/default/controls/archive_spec.rb

 control 'mongodb components' do
   title 'should be installed'

+  describe service('mongod') do
+    it { should be_running }
+  end
   # describe package('unzip') do
   #   it { should be_installed }
   # end

and I still have a problem with service not running

  ×  mongodb components: should be installed (1 failed)
     ×  Service mongod is expected to be running
     expected that `Service mongod` is running

[daks]

FYI: even removing those onlyif, I don't have mongod service running, even if the converge pass

Testing daks test, and getting the same error, but...

Salt states in is running while applying...

                 ID: mongodb-service-running-database-mongod
           Function: service.running
               Name: mongod
             Result: True
            Comment: Service mongod has been enabled, and is running

              ----------
              mongod:
                  True

And tests states it is not

  ×  mongodb components: should be installed (1 failed)
     ×  Service mongod is expected to be running
     expected that `Service mongod` is running

Removing that test. If anyone has ideas about it...
