Allow filtering pod logs by regex

[dhirschfeld]

Summary

The ability to filter pod logs is very useful however it appears that you can only filter by simple strings. This feature would be even more useful if you could provide a regex to use to filter the logs.

Motivation

e.g. I want to filter out DEBUG and TRACE logs, or only include WARNING or ERROR logs, or generally to filter by more than one condition. Other examples might be to only see logs from one of several functions or urls etc.

Proposal

It looks like re.Match could be used here instead of strings.Contains?

lineContainsFilter := strings.Contains(entry.line, literal)

It appears the original feature was implemented in #5319
