Option to restrict logging further

[klasvo]

Hi,

it would be nice if there was an option to restrict logging further:

• either completely deactivate logging
• specify more than one path with LOG_IGNORE_PATH

The latter could be implemented by doing a regex match instead of a string comparison.

Without requests being logged, one could assure that no personal or secret data gets leaked.

Cheers

I've got a PR going and also published a temporary tag to Docker Hub if you want to test:

docker pull mendhak/http-https-echo:issue80

Examples:

# Ignore a single path    
docker run -e LOG_IGNORE_PATH=/ping -p 8080:8080 -p 8443:8443 --rm -t mendhak/http-https-echo:issue80
# Ignore multiple paths
docker run -e LOG_IGNORE_PATH="^\/ping|^\/health|^\/metrics" -p 8080:8080 -p 8443:8443 -t mendhak/http-https-echo:issue80
# Ignore all paths
docker run -e LOG_IGNORE_PATH=".*" -p 8080:8080 -p 8443:8443 -t mendhak/http-https-echo:issue80
