Validate that cronjob names are 52 characters or less
**What this PR does / why we need it**:
Right now when you create a cronjob with a name longer than 52 characters, creation will succeed but the cronjob controller will create Job objects with names longer than 63 characters. Jobs cannot have names longer than 63 characters, so the cronjob will never be able to run any jobs.
