This way should be easier to support new protocols

d377181b25 add a new configuration section for HTTP clients 
HTTP clients are used for executing hooks such as the ones used for custom

1d917561fe sftpd: add support for upload resume 
we support resume only if the client sets the correct offset while resuming
the upload.
Based on the specs the offset is optional for resume, but all the tested
clients sets a right offset.
If an invalid offset is given we interrupt the transfer with the error
"Invalid write offset ..."

See https://github.com/pkg/sftp/issues/295

This commit add a new upload mode: "atomic with resume support", this acts
as atomic but if there is an upload error the temporary file is renamed
to the requested path and not deleted, this way a client can reconnect
and resume the upload

e7eb3476b7 dataprovider: remove transaction for quota update 
The update is atomic so no transaction is needed.
Addionally a transaction will ask for a new connection to the pool
and this can deadlock if the pool has a max connection limit too low.

Also make configurable the pool size instead of hard code to the cpu number.
