Remove transformers from pipeline.yaml

In Liberty we cannot run more then one notification agent in cloud
without coordination. So, we have several approaches how to
solve this problem:

1. Run one notification agent under pcs.
   pros: we keep transformers
   cons: one notification agent is not enough for big envs

2. Change config and not to gather "delta" and "util" by default
   pros: ok from performance PoV; no changes in puppet
   cons: transformer-based meters are not generated

We've chosen the second approach. If tranformers will be needed, we can
deploy our redis plugin, switch on coordination mode and add transformers
back to config.
Removed unit tests tested default pipeline.cfg, not the functionality.
That is why is is safe to remove them.
