storage: add redis-socket scheme for connect to redis with unix socket

[ru-asdx]

Ref: #595

address of redis storage now can be specified as :

redis_brocker: "redis-socket://pwd@/run/redis/redis.sock?db=0"

Nice, thank you!

I've added one comment. Also, there's documentation, could you add a note about the addresses in there, too, please? And maybe in the example config as well.

Don't worry about CI failing. We'll fix it at some point and merge then.

Thank you :)

[mrd0ll4r]

LGTM, thanks!

Again, the CI is broken, we'll fix it at some point. Because of that I won't merge it now, just leave it open, we'll come back to it :)

[mrd0ll4r]

Hello! The CI is fixed :) If you rebase this PR, we can probably merge it. Thanks again!

[mrd0ll4r]

Sorry, I missed this earlier: Can you squash your two commits into one and give it a name of this schema:

<subsystem, e.g. storage>: <what changed>

As described here in more detail.

Sorry for missing that last time! The changes look good.

[ru-asdx]

is something wrong again?

[mrd0ll4r]

Oh, sorry, this fell under the table. Changes look good, as before :) We have a data race which will probably block CI, again... really sorry.

Anyway, just leave this open, we'll fix it eventually and merge. Thank you!
