Issue when deploying F5-Analytics app using f5.analytics.v3.7.1 template to send logs to SPLUNK

Hi John,

I don't know much about the splunk integration. I found the Python script and readme files on a different github link.

https://github.com/plcharbonneau/f5-application-services-integration-iApp/tree/release/v2.0.002/scripts

I've added them here as link can change/remove.

 README.deploy_iapp_bigip:

deploy_iapp_bigip.py
	Deploy an iApp to a BIG-IP system using the iControl-REST API

This script uses the F5 BIG-IP iControl REST API to create a specific
instance of an iApp deployment.

The script supports:
 - Deployment/Redeployment of an iApp using JSON template files
 - Hierarchical definition of a deployment using multiple JSON files
   - A JSON template can specify a 'parent' file to inherit properties from
   - No limit to the number of levels of inheritence
 - Automatic selection of the latest version of the appsvcs_integration_iapp 
 - Specification of partition, traffic-group, device-group and other global items

Sample template files are included in the 'deploy_iapp_samples' directory
that implement a three-level hierarchy and deploy a HTTPS or HTTP virtual 
server using the appsvcs_integration_iapp.  The following table describes 
the contents of the sample files:

 sample_defaults.json: Default values for all the fields contained in the iApp
 sample_https.json:    Default values for a HTTPS service (parent: sample_defaults.json)
 sample_myhttps.json:  Top level definition of the service (parent: sample_https.json)
 sample_http.json:     Default values for a HTTP service (parent: sample_defaults.json)
 sample_myhttp.json:   Top level definition of the service (parent: sample_http.json)

To deploy the sample_myhttps.json template a command like this can be used:
 
 cd deploy_iapp_samples
 python ../deploy_iapp_bigip.py -i <BIG-IP mgmt IP> -u <username> -p <password> sample_myhttps.json

By default the script will automatically save the system config.  This 
behaviour can be disabled by using the '-d' option.

For further options please run the script with the --help argument
