Redundant warning " implement duration caching in GstBin "

[rland]

Hi，GStreamer developers,
In the <Warning> log level, we can always see the following large number of warning output,especially in embedded devices, occupied too much CPU resources.

it seems that  have already acrossed several release version，and hope next version,this issure will be repaired?

This is not a warning anymore but a "FIXME". It's an optimization that
was lost from 0.10 to 1.0, but not really important. Just nice to have
if someone wants to implement it (there are some complications to keep
in mind, as always with caching).

Sebastian,thanks for your patience.
As you said above, before optimizing it, maybe if we can  make it print once instead of  always print it will be better.
