Refuse credentials in a storage URL's endpoint or rclone remote name (closes #322)

storage_url refused only the outer URL's userinfo and unknown query
parameters. Userinfo inside the s3 endpoint= value, and rclone's
remote,param=value parameters in the remote name, were accepted and
then printed by info, remote info and snapshot create. Both are now
refused without echoing the value: a host name never contains "@", and
an rclone remote name never contains a comma. The comma is checked
before url.Parse, because url.Parse refuses a name such as
":s3,secret_access_key=..." or "x,secret=a:b", and its error prints
the name from the colon on. The rclone case has its own error pointing
at rclone config, since the existing credentials error names the s3.*
keys.
