Fix docs markup consistency

This commit fixes docs consistency about markups, mainly. Originally,
some of command options were written with strong emphasis. However,
double dashes are converted to a single dash with it. And this commit
also fixes some inconsistencies and weird indentations.

 For example if you were trying to remove the test with the id:
-tempest.api.compute.admin.test_flavors_negative.FlavorsAdminNegativeTestJSON.test_get_flavor_details_for_deleted_flavor
+``tempest.api.compute.admin.test_flavors_negative.FlavorsAdminNegativeTestJSON.test_get_flavor_details_for_deleted_flavor``
 you would run the following:
 
-#. run: "mysql -u query -p -h logstash.openstack.org subunit2sql" to connect
-   to the subunit2sql db
-#. run the query: MySQL [subunit2sql]> select * from tests where test_id like

    generate it into the etherpad.
