Support slurmrestd jwt auth

[c-vinet]

Hello, slurm-web does not currently support slurmrestd's jwt authentication (see slurm docs). This pull request is a naive attempt to support it using the X-SLURM-USER-* request headers. I tested it on our infrastructure which uses jwt authentication and it seems to work. Let me know what do you think of it.

Hello @c-vinet, thank you for this contribution! Note this is a good first step for #313.

I guess you setup in configuration a JWT you previously obtained with scontrol for slurm user with an unlimited/infinite lifespan, right?

[c-vinet]

Hi @rezib, yes i used scontrol token to create the JWT for the root user ( it should work with any slurm admin user ). I didn't think about it much but indeed this authentication mechanism will be needed for slurmrestd over TCP/IP.

I am also looking for this feature. I would like to deploy slurm-web outside slurm clusters and would love to talk over TCP using APIs. Did anyone tested this patch?

@satishdotpatel It looks like what you need is actually #313.
