File holder component

[jakubklimek]

Often enough, when I am debugging in LP-ETL, I use Textholder to put my debugging data in. This works fine for text-based formats such as RDF , CSV, XML and JSON. It does not work for binary files such as XLSX, even though the use case is the same.

Therefore, a new component, file holder, would be useful. It would allow me to upload a file, and it would store it (probably as hex64binary) in the configuration, the same way TextHolder does for texts.

There is a risk that a user will upload large files, making the pipelines and configurations large, but it is the same risk as with TextHolder where one can also input a large text, making everything slow.

Without such component, I must upload the file either to the LP-ETL server, or somewhere downloadable, which is quite a hassle for simple debugging.
