[bug] using args.partition causes unknown flag

[tkam8]

Description

When running below command to launch chart to deploy the controller, k8s controller pod goes from "Error" to "CrashLoopBackOff " and never gets created.

helm install --set args.bigip_url=1.2.3.4 --set args.partition=kubernetes --set bigip_login_secret=bigip-login --set serviceaccount=k8s-bigip-ctlr f5-stable/f5-bigip-ctlr

Repro:

1. Install k8s
2. setup flannel and setup BIG-IP dummy node
3. setup bigip serviceaccount as necessary
4. setup secret for bigip login
5. install helm client and tiller
6. run helm install command as shown above using parameter "args.partition"
7. workaround is to change the parameter name to "bigip_partition"

Expected Behavior:
Pod gets created

Actual Behavior:
error

Request: please update the documentation if bigip_partition should be used as the parameter name when using the --set option.

Update:

upon further inspection, it looks like "helm inspect values" shows the right parameter name so should be sufficient documentation.
I don't know where "args.partition" is valid, though. Any ideas?
