fix: sink retry log not showing unit of time and the correct level

[StewartJingga]

Is your feature request related to a problem? Please describe. 1. Wrong Log level on sink retry notification. It should be warn | error instead of info.

2. Also it does not show unit of time, like the following

retrying sink in 5000000

Describe the solution you'd like 1. Change log level on sink retry to warn or error.

2 And log should show unit of time e.g.

retrying sink in 5000000ms

Also it would be nice to make time to be more readable like:

• 5s
• 5,000,000 ms
• 25m
