For associate sites only, parse_skexport returns incorrect private key for tokens

[mpackard]

current:
tokens = {"site_admin_privatekey": "JWTSIGNING_ADMIN_PRIVATEKEY"}

should be (e.g. for UH)
tokens = {"site_admin_privatekey": "JWTSIGNING_UHADMIN_PRIVATEKEY"}

Need to figure out how to handle for all cases.

Might have to add a new variable, i.e.
"if site_type = 2, must specify name of admin tenant", like "uhadmin"

Also might have to variablize the deployer version of parse_skexport and uppercase the admin tenant name

in host_vars we can set this, which might help:
skadmin_service_tenant_id: uhadmin
