Is your feature request related to a problem? Please describe: When using tiup cluster check command, there are one important check items that are not printed

Describe the feature you'd like: I hope that after the tiup cluster check command is executed, the I/O scheduler configuration information will be printed out, whether it is correct or not.

Why the featue is needed: Do not print this information, it is easy to miss to check

Describe alternatives you've considered: Pass the parameter check and print pass, if it fails, print the current value and mark it as warn
