4.9 integration tests are full of below error:

[odo]  ✗  1 error occurred:
[odo] 	* devfile contains multiple endpoint entries with same TargetPort: 3000 

I think #5407 is addressing this. @valaparthvi WDYT? I see your PR failing with bunch of:

[odo]  ✗  URL creation failed:
[odo] 	- port 8080 already exists in devfile endpoint entry under container "py-web"
