test-network-k8s: Introduce initial support for BFT orderers (#1294)

This patch adds initial support for BFT orderers in the test-network-k8s. When `TEST_NETWORK_ORDERER_TYPE` is set to `bft`, the network launches four orderers configured with SmartBFT. Signed-off-by: Tatsuya Sato <tatsuya.sato.so@hitachi.com>

+#   SECTION: Capabilities
+#
+#   - This section defines the capabilities of fabric network. This is a new
+#   concept as of v1.1.0 and should not be utilized in mixed networks with
+#   v1.0.x peers and orderers.  Capabilities define features which must be
+#   present in a fabric binary for that binary to safely participate in the
+#   fabric network.  For instance, if a new MSP type is added, newer binaries
+#   might recognize and validate the signatures from this type, while older
+#   binaries without this support would be unable to validate those
+#   transactions.  This could lead to different versions of the fabric binaries
+#   having different world states.  Instead, defining a capability for a channel
+#   informs those binaries without this capability that they must cease
+#   processing transactions until they have been upgraded.  For v1.0.x if any
+#   capabilities are defined (including a map with all capabilities turned off)
+#   then the v1.0.x peer will deliberately crash.
