[FAB-4226] Upgrade example app to beta level

Upgrading the sample app to latest master head, with the goal to
support the beta release.

Simplified code paths. Eliminated the need for the "x-access-token"

when the beta is to be released,
the following temporary changes will be updated:
- dependencies on "fabric-client" and "fabric-ca-client" will be
  the beta version, instead of the current file:// paths
- images in artifacts/docker-compose.yaml will be updated to
  the published beta tag instead of "latest"

 Once you have completed the above setup, you will be provisioned a local network with following configuration:
 
 * 2 CAs
-* A kafka orderer
+* A SOLO orderer
 * 4 peers (2 peers per Org)
 
 #### Artifacts
-* Crypto material has been generated using the **cryptogen** tool from fabric and mounted to all peers, the orderering node and CA org containers. More details regarding the cryptogen tool are available [here](http://hyperledger-fabric.readthedocs.io/en/latest/getting_started.html#using-the-cryptogen-tool).
-* An Orderer genesis block (orderer.block) and channel configuration transaction (mychannel.tx) has been pre generated using the **configtxgen** tool and placed within the artifacts folder.
