http: Duplicate slashes in the path

[euroelessar]

Description:
Envoy currently does not collapse multiple slashes in a row into one for request uri paths.
For example: //a/b/c or /a///b/c into /a/b/c.

Both Nginx and Apache do optionally perform such operation, is it something Envoy could consider to do as well?
