Add timeout for helm commands

[Angie Wang]

Brief Description
-----------------
Sysinv runtime manifest apply triggers the application reapply evaluation to regenerate helm application overrides. In the case that the application has user overrides, "helm install --dry-run" command is invoked to merge overrides. In general, "helm install --dry-run" is relatively quick as it doesn't need to request the cluster. But it's possible that it hangs in a bad situation, it could cause the runtime puppet manifest apply failed and Sysinv RPC timeout. For the robust, the command as other helm commands in sysinv/helm/utils.py should be improved to set with an operation timeout.

    Add timeouts for helm commands

    Armada is still connecting tiller to manage releases. To make it
    more robust, we should set "--tiller-connection-timeout" to the
    helmv2 commands to prevent helm commands hang in case tiller is
    not running or having connection issue. An additional operation
    timeout is added for some commands as well to enhance the robustness.

    Remove the space of the helm command argument

    Remove the space of the helm command argument
    "--tiller-connection-timeout 5" as the space may
    cause the argument to be unknown sometimes.
