[Bug]: Intermitent failure on local make up

[KevinMind]

What happened?

After merging mozilla/addons-server#22929

2 bugs arose that did not surface in testing.

1. the elastic monitor does not return an error status if it cannot reach elastic leading to false positive
2. os.getuid() returns the UID of the current process user. our entrypoint.sh script modifies that UID and sometimes that happens after executing initialize.py leading to false negative django checks for the correct uid.

What did you expect to happen?

We should handle these cases.

Is there an existing issue for this?
