Because of some errors with cyclical imports for the chaincode package
tests which are not written as _test packages, we need to define a
structure to represent a chaincode which is not the
ChaincodeDeploymentSpec but which is also not inside of the chaincode
package.  Defining this in the lifecycle portion makes sense, so as a
prerequisite, moving lifecycle from the chaincode package, to a
subpackage called lifecycle.

Note: This introduces some stuttering, that will be remedied in a later
CR.
