Adding a user agent about papyrus

[dan-starkware]

Consider using a crate such as os_info.

I think we should close this one.

Any recommendation how I can retrieve OS information ?

[ptisserand]

Here is the aggent I received when running a local netcat + config.yaml modified to use my localhost:

$ netcat -l -p 5555
GET /feeder_gateway/get_block HTTP/1.1
accept: */*
user-agent: papyrus/pre-release (Arch Linux)
host: localhost:5555

Does it seems fine?

[dan-starkware]

Yes, consider adding some more info to the system information (distribution, version, architecture, etc.)

[ptisserand]

Version and architecture provided by os_info have been added.

GET /feeder_gateway/get_block HTTP/1.1
accept: */*
user-agent: papyrus/pre-release (Arch Linux; Rolling Release; 64-bit)
host: localhost:5555
