Feature request: build log formatting options

[apex-omontgomery]

These are feature requests to improve codefresh logs <build_id>

It's my opinion that these features are essential to make interacting with build logs useful:

1. The ability to turn off color codes using a flag
2. Line endings are using CRLF in a in a peculiar way that causes dos2unix to fail.

$ codefresh logs $BUILD_ID > data.out
$ dos2unix data.out
dos2unix: Binary symbol 0x1B found at line 33
dos2unix: Skipping binary file data.out

3. Filtering/ selecting of individual steps is only possible through post processing. This makes it difficult to parse the output, when you only need logs from a single failing step.
4. The ability to output formatting as json (this would solve 3.)
