Review request for Ambari, Andrew Onischuk, Jaimin Jetly, and Yusaku Sako.


Bugs: AMBARI-10483
    https://issues.apache.org/jira/browse/AMBARI-10483


Repository: ambari


Description
-------

In some environments, the Kerberos Client packages are already installed on the machines and
the operator does not want to install the OS kerberos client packages.

Ambari should provide an option in the Enable Kerberos Wizard to not install Kerberos Clients
on the machines.

Under the Advanced krb.conf section, at the bottom, expose this checkbox for this option:

```
[ ] Do not install Kerberos Client packages
```

After enabling Kerberos, this configuration option should be visible under the Services >
Kerberos > Configs.

This would instruct Ambari to not install the Kerberos Client packages when installing the
Kerberos Client component. We can still have Ambari install the Kerberos Client component,
just circumvent the install packages.

**Note:** If selected, it is assumed that the user will install packages containing executables
compatible with the MIT Kerberos 5 version 1.10.3

Testing
-------

Manually tested.

No unit tests updated since lifecycle install_packages method is mocked.

Local ambari-server python tests passed:
