Previously, "run dir" was used to place a number of file and config on dataDirHostPath. Now, since a lot of configs and options have moved either on the OSD's startup CLI line or remove with bluestore we don't need to change the default. Also, it was confusing for user and difficult to find the socket. The is is not breaking any config in dataDirHostPath since all the elements (keyrings) are hardcoded in the config file.
