Make log format for requests configurable
Add the log_msg_template option in proxy-server.conf and log_format in a/c/o-server.conf. It is a string parsable by Python's format() function. Some fields containing user data might be anonymized by using log_anonymization_method and log_anonymization_salt. Change-Id: I29e30ef45fe3f8a026e7897127ffae08a6a80cd9

The proxy logs contain the record of all external API requests made to the

Some keywords, signaled by the (anonymizable) flag, can be anonymized by
