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.

 Set-up is split in a series of steps (setup stages), which can be overwritten
 by test classes. Set-up stages are:
 
-- `skip_checks`
-- `setup_credentials`
-- `setup_clients`
-- `resource_setup`

 Tear-down is also split in a series of steps (teardown stages), which are
 stacked for execution only if the corresponding setup stage had been
 reached during the setup phase. Tear-down stages are:
