Retrieves a cached value by key, generating it if it does not exist.

This implementation does not support TTL. Values will remain valid for the lifetime of this
instance, or until removed.

@since [*next-version*]

@param string|int|float|bool|Stringable $key     The key to retrieve the value for.
@param null|callable|mixed              $default The value to return if key isn't found. If this is a callable,
it will be invoked and the result will be used as default.
@param null|null|int|string|string      $ttl     The number of seconds for the value to be considered valid.
If null, the behaviour is undefined, and the value may live indefinitely.

@throws InvalidArgumentException    If creator is not a callable, or TTL is invalid.
@throws OutOfRangeException         If the key is invalid.
@throws ContainerExceptionInterface If problem reading or writing the value.
@throws RuntimeException            If value could not be generated.

@return mixed The cached value.
Retrieves a cached value by key generating it if it does not exist .
