> OM shutdown when creating key with malformed characters

> Key: HDDS-5455

> In OzoneManagerStateMachine.runCommand, if there is a Runtime exception, OM
> will be terminated.
> In our case, the user would like to create an object with malformed
> characters in keyName, and the following error happened and throws an
> InvalidPathException, which is a Runtime Exception causing the OM's shutdown.
> Normally this wouldn't happen, since a user can not easily create an invalid
> keyName with UTF-8. It happened in our environment because our OM started
> with the property of "file.encoding" and "sun.jnu.encoding" set to
> "ANSI_X3.4-1968", and it's easy for the user to write a invalid keyName.
> This issue can be avoided when running in a good environment, but it's still
> not reasonable that a client create key operation causing the shutdown of OM.
> This ticket is to check the keyName if it fits the current encoding of OM, if
> not just return the OMException of "INVALID_KEY_NAME".
