Support action labels as input to execution:get-step-log and execution:get-quality-gate-result

As described in #226, it would be helpful if the label (i.e. "Build Image") could be provided as the action option to these commands.

This is likely dependent upon https://github.com/oclif/parser/issues/162. It is doable without that change in @oclif/parser, but option validation would have to be reimplemented so it would be best if @oclif/parser supported that directly.

首先检查 execution:get-step-log 和 execution:get-quality-gate-result 命令的入口点，然后阅读 #226 中描述的依赖项以及链接的 @oclif/parser issue。完成的标准是两个命令都能将诸如 "Build Image" 这样的操作标签作为 action 选项接受，同时保留选项验证。
