[Feature request] Ability to personnalize URI

[MayannF]

Hi,

I would like to suggest a simple feature making possible to expose s-pdf behind a reverse proxy using subfolders.

I managed to make this work on a test container by simply adding
server.servlet.context-path=${CONTEXT_PATH:/} to application.properties.
With this, if I run the container with option -e CONTEXT_PATH=/s-pdf, the webapp is fully accessible from mydomain.com/s-pdf

If no option is passed, it keeps the default root path /.

I'm very new to git so I hope this is an appropriate contribution !
