add map inside stream

[cs-zetsu]

Is your feature request related to a problem? Please describe

We use the stream module for reverse proxy ssl connection, so we need something like this:
`
stream {

upstream web1 {
    server https://thatserver.org;
}
upstream web2 {
    server https://otherserver.org;
}
upstream thisone{
    server https://localhost:8443;
}

map $ssl_preread_server_name $name {
    thatserver.org web1;
    otherserver.org web2;
    default thisone;
}

server {
    listen 443 ;
    listen [::]:443 ;

    proxy_pass $name;
    ssl_preread on;
    proxy_protocol on;
}

}
`

AFAK, in http module there is the map statement:
map: hash_bucket_size: 128 hash_max_size: 4096 mappings: - string: $http_host variable: $name ...

But there is none in stream module.

Describe the solution you'd like

use the map in stream module as there is in http module

Describe alternatives you've considered

For now, we will use the custom_directives, or try to do it using a local branch

I'll add it to the backlog! In the meantime, I would suggest using the custom_directives parameter to workaround not having map support in the stream context 😄

[cs-zetsu]

Yes, for now we're using the custom-directive and is working

custom_directives
- map $ssl_preread_server_name $name {
- example.site1.srl web1;
- example.site2.srl web2;
- default none;
- "}"

P.S. Tab, is wrong, i could not understand how to use the "code" in markdow... sorry XD

No worries! Glad you managed to get it working!
