Solve Bugs and Add Redis Key Prefix Process

[zhaojjiang]

• replace functions array_get() and array_has() with Illuminate\Support\Arr::get() and Illuminate\Support\Arr::has(), because these two functions has been deprecated since Laravel 6.0. (The two Arr::* functions were both found in Laravel 5.*).
• change keys modify page of string type submit way from form to pjax to avoid the refresh bug after update.
• the redis client maintain key prefix automatically, so the redis-manager need to separate show (with prefix) and real process (without prefix)
  • apply key filter with prefix in global pattern in index show page.
