Credential reset allows the use of weak passwords for Service Principals

[mattsmall1972]

az feedback auto-generates most of the information requested below, as of CLI version 2.0.62

Describe the bug
When creating a service principal, the password by default is not allowed to be set by the end user in order to prevent weak passwords. However, this feature was not ported into the credential reset command and therefore weak passwords are still possible.

Documentation: https://docs.microsoft.com/en-us/cli/azure/create-an-azure-service-principal-azure-cli

To Reproduce
az ad sp credential reset --name "ResetClientSecret" --credential-description CliSecViaCLI --password ABC123
