Revert: Blueprint "bp/distributed-serialization"

Revert: Blueprint "bp/distributed-serialization"

Until upstream fixes bug [1], partially revert blueprint
implementation [2]:
- fuel-agent: no-op, we overwrite fuel_bootstrap_cli.yaml anyway;
- fuel-library: no-op, keep newly added port config in place;
- fuel-web: revert all blueprint related changes;

NOTE: When this blueprint becomes part of Fuel@OPNFV, we need to
      update our "fuel_bootstrap_cli.yaml".
