Fix color bug: not intense_cyan but bright_cyan

[ANSI array](https://github.com/sonots/foreman/blob/1d2bcdbc56acd2f1d39880abf6211267bea33721/lib/foreman/engine/cli.rb#L7) is defined as below. `intense_cyan` should be `bright_cyan`. Same for others. 

    ANSI = {
      :reset          => 0,
      :black          => 30,
      :red            => 31,
      :green          => 32,
      :yellow         => 33,
      :blue           => 34,
      :magenta        => 35,
      :cyan           => 36,
      :white          => 37,
      :bright_black   => 30,
      :bright_red     => 31,
      :bright_green   => 32,
      :bright_yellow  => 33,
      :bright_blue    => 34,
      :bright_magenta => 35,
      :bright_cyan    => 36,
      :bright_white   => 37,
    }
