When creating or updating a remote through the rc api (config/create,
config/update), parameters whose name starts with the ephemeral prefix
"config_" (for example config_template_file and config_template used to
customise the OAuth success page) were silently ignored.
updateRemote sets each supplied parameter into the config mapper, but
skips the "config_" prefixed keys so they are never written to the
config file. That guard is correct, because the mapper's setter writes
to the config file and these values are ephemeral. However backends read
these values back from the mapper (oauthutil reads config_template_file
and config_template via m.Get), so dropping them entirely meant the
values could never reach the backend and the default template was always
used.
Collect the ephemeral parameters into a separate map and add it to the
mapper as a getter overlay at PriorityNormal after the loop. The values
are now readable through m.Get without being written to the config file,
which is the same approach rclone authorize already uses to expose a
template supplied on the command line.

DeleteFile always passes a nil backupDir to DeleteFileWithBackupDir, so
it never honours --backup-dir. The previous comment said it would move
the file into the backup dir when --backup-dir was in effect, which does
not match the code. Update the comment to state that DeleteFile always
deletes and that callers should use DeleteFileWithBackupDir when
--backup-dir support is required.
Also document on DeleteFileWithBackupDir that the backupDir is found with
BackupDir, which is relatively expensive, so it should be looked up once
outside any delete loop rather than per object.
