Allow non-word characters in vs_bridge external_ids

Currently, the type enforces a regex for vs_bridge
external id values that is way to strict. Essentially
that entries are \w*=\w*.

Bridge external ids commonly include non-word characters
, like '-' (ie: br-ex).

This patch updates the parameter checking to allow
any non-whitespace characters.
