Added splitter as a service

Added splitter as a service. Make sure we use the config parameters to set split_size.

Get this error

[2015-03-18 13:42:01] app.CRITICAL: [dizda-backup] Unexpected exception. {"exception":"[object]

Seems now doesn't try to upload split files but main file. Checking...

[ndoulgeridis]

The splitter creates *_parts files, this should be passed to file services (dropbox, google drive etc) and not the original one.

[Nyholm]

Got it.. updating in a minute

[ndoulgeridis]

nice!

[Nyholm]

The drawback of this solution is that client authentication must be done for every part of the archive.

An alternative solution is to make sure the clients can accept a list of files and make each client try to optimize the upload process. But IMHO is client authentication a small fractions of the total time for the backup process.

[ndoulgeridis]

Hmm yes indeed but I don't know if clients allow multi file uploading at once, need to research but as you already mentioned the way it is implemented now wont hurt performance too much.

[ndoulgeridis]

Works fine btw!!!!

[Nyholm]

Okey, Great. Thank you.

[dizda]

Great, so the splitter is now working fine? So we should write missing tests, and we'll be able to merge into master then release the new version.

[ndoulgeridis]

Yes in my copy seems working fine, it successfully uploaded a split backup to Dropbox

[Nyholm]

Thank you for merging
