standardize support uploads customer name

[Anthony Howe]

Standardize on the support name for the cluster:

av0x2dCUSTOMER0x2dRESOURCE_GROUP-CLUSTER

The name is separated by separator 0x2d and must match the following regular expression ^av([-a-zA-Z0-9_]*[a-zA-Z0-9])?$ and spaces can be converted to _.

The following lists each of the 4 parts:

1. av - this represents that this is a dynamic avere cluster
2. CUSTOMER - this is a customer name supplied in variable support_uploads_company_name or if not specified, the first stanza (all lowercase) of the subscription id.
3. RESOURCE_GROUP - this is the resource group specified by azure_resource_group and is transformed to match the regular expression above.
4. CLUSTER - this is cluster name specified by vfxt_cluster_name

The combination of resource group and cluster name always ensures a unique cluster name.

Once cluster is up, and specify use support.modify customerId to apply the name av0x2dCUSTOMER0x2dRESOURCE_GROUP-CLUSTER

For testing, run the following commands on the cluster:

• lsu clustername - this shows the cluster name
• lsu gsiInfo custID - this shows the support name
