https://perconadev.atlassian.net/browse/PS-9195 Added support for JS Console Log to our implementation of JS Stored Programs. Users can now use console.log() and other calls described in the JS Console Standard in their JS Stored Programs to log messages to debugging console. And then access to buffered output of the console through UDFs. The main purpose of this tool is to simplify debugging and profiling of JS routines. A few things to note: - Most of calls described in JS Console Standard are supported. - Each connection and user pair gets its own Console instance (similarly to JS Contexts). - While JS_GET_CONSOLE_LOG() UDF provides access to simple, plain version of console output (similar to Node.JS), JS_GET_CONSOLE_LOG_JSON() provides access to extended, more structured version of console log in JSON form. - We also support clearing the console log from SQL session through JS_CLEAR_CONSOLE_LOG() UDF. Added test coverage for this functionality.
