ANSI escape sequences are not well displayed in `jc logs`

[Zhaofeng Miao]

Some strings [32m and [0m that control the font format are not well displayed.

yes, it is a server-side problem.

Server-side should add JINA_LOG_NO_COLOR tags on every running flow:

JINA_LOG_NO_COLOR=1 jina flow --uses toy-flow.yml

This will not add ANSI color chars to the logs.
