Splunk SDK has dependencies not satisfied by Splunk Python

[573927]

The Splunk SDK currently has a requirement for deprecation. However, the Python version that is bundled with Splunk Enterprise does not contain deprecation and does not contain packaging, which is a dependency of deprecation.

It is common to use the Splunk SDK for developing Splunk apps (see https://dev.splunk.com/enterprise/docs/developapps/#Splunk-tools). When using version 2.x of the Splunk SDK in apps, those apps will not function correctly because of the missing dependency. It cannot be safely assumed that Splunk enterprise administrators would manually install those dependencies. I would argue that the Splunk SDK should not contain any dependencies that are not satisfied with the Python version that is bundled with Splunk.
