Cannot run multiple instances of the EGA Fuse client on the same machine.

[pneerincx]

Dear developers,

We use the EGA Fuse client for access to specific datasets for the Solve-RD project: works great :) This is inside a folder for this project on an HPC cluster. Now we want to do the same for other datasets for another project (Cineca). Obviously that has to be mounted in a different location and with different permissions, but it is on the same HPC cluster. Running a second instance of the EGA Fuse client fails, because port 8080 is already in use. Would it be possible to add another commanline option to specify the port number in addition to mountpoint and credentials, so we can run multiple instances of the EGA Fuse client?
The error we get is this:

$> sudo journalctl -u ega-fuse-client@cineca

This is correct as we already have another instances of the EGA Fuse client running for Solve-RD:

@pneerincx check the newest version, we have dropped the web-server and will not require to reserve any port. Regards.

@jorizci Thanks, we'll update to 2.1.0.
