swagger-codegen generate should not generate WARN io.swagger.codegen.DefaultCodegen - Empty operationId found for path: post /foo

Description

swagger-codegen generate should not generate WARN io.swagger.codegen.DefaultCodegen - Empty operationId found for path: post /foo

since the spec does not define operationId as required and swagger-codegen can autogenerate value for it.

Or at least a command line option to silence the warning should be provided because now it only makes more difficult to spot issues.

The warning would also be more useful if it shown line number and possibly column. While not essential in this case (the method and path is provided), this threw me off a bit especially at the beggining when I had a lot of warnings.

Command line used for generation

JAR=".../swagger-codegen.git/modules/swagger-codegen-cli/target/swagger-codegen-cli.jar"
java -jar "${JAR}" generate -i ~/sscce.yaml -l html2 -o foo

outputs:

swagger-codegen generate -i sscce.yaml -l html2 -o sscce.html
[main] INFO io.swagger.parser.Swagger20Parser - reading from sscce.yaml
[main] WARN io.swagger.codegen.DefaultCodegen - Empty operationId found for path: post /foo. Renamed to auto-generated operationId: fooPost
[main] INFO io.swagger.codegen.AbstractGenerator - writing file /home/yac/sscce.html/index.html

Start with the generate command and the warning emitted by io.swagger.codegen.DefaultCodegen when the sample sscce.yaml has no operationId for POST /foo. Determine whether the missing operationId warning should be suppressed or made configurable, and whether location details are feasible. Done means generation still produces the autogenerated operationId while the warning behavior matches the selected resolution.
