I'm right there with you Bryan... To get past this I searched through all the SA's and TA's looking at the inputs.conf.spec files. I found that the stanza Splunk_TA_vmware was expecting lives in the SA-VMNetAppUtils inputs.conf.spec file (SA-VMNetAppUtils/README/inputs.conf.spec). I copied the necessary stanza from there, made a backup copy of the inputs.conf.spec file in Splunk_TA_vmware, and then pasted the missing stanza into the inputs spec file. From there I ran my cluster bundle apply and saw no errors.
For reference, here is the missing stanza:
`[dm_accel_settings://default]
* Configure an input for enforcing data model acceleration settings automatically
* when another app is installed. Note that only one app at a time should define
* the acceleration settings for a given data model. Usually this is the "primary"
* app for the suite of apps on the system, e.g. SplunkEnterpriseSecuritySuite.
acceleration = [true|false]
* True if the data model should be accelerated.
manual_rebuilds = [true|false]
* If true, changes to the datamodel will not automatically rebuild the HPAS
* data store.`
