ZCC configuration and usage docs does not differentiate between installing from source code and package

[[e-mail]]

Currently ZCC supports two kinds of installation: from source code or from package downloaded from IBM FixCentral.
We told the user of Fixcentral to refer to the opensource ZCC doc for usage information. However, the configuration/usage steps described in ZCC docs only considered the scenario of installing from source code, for example, file path may be different.

Take the following section as an example:

5.2.4.1. Configuration of zvmguestconfigure on RHEL6.x and SLES11.x

Perform the following steps:

    Log on your BYOL, and copy the zvmguestconfigure script that is located at <zvmsdk_path>/python-zvm-sdk/tools/share/zvmguestconfigure to your zLinux, where zvmsdk_path can be found at section z/VM SDK install

We need to scan the doc and make the difference.
