       Sets  the  "authMechanism"  URI  option, such as "SCRAM-SHA-1" or "GSSAPI", after the URI has been parsed
       from a string.

       Updates the option in-place if already set, otherwise appends it to the URI's bson_t of options.

       • uri: A mongoc_uri_t.

       • value: The new "authMechanism" value.

       Returns false if the option cannot be set, for example if value is not valid UTF-8.
