[Feat]: Streaming path information in node info

[ktsaou]

Problem

We need at the node info sidebar, a way to show streaming topology.

/api/v3/nodes provides the streaming path per node, like this:

            "streaming_path":[{
                    "hostname":"manjaro",
                    "host_id":"afc967e2-2bd5-11ee-aa25-525400f78edf",
                    "node_id":"9607839a-a950-42b8-8f3e-4f6a92e5e6fa",
                    "claim_id":"10fba0b8-8f08-48c0-9c14-e3c7f17e19a2",
                    "hops":0,
                    "since":1730624722,
                    "first_time_t":1703876400,
                    "start_time":1337,
                    "shutdown_time":1175,
                    "capabilities":["V1","V2","VN","VCAPS","HLABELS","CLAIM","CLABELS","LZ4","FUNCTIONS","REPLICATION","BINARY","INTERPOLATED","IEEE754","ML","DYNCFG","SLOTS","ZSTD","GZIP","BROTLI","PROGRESS","NODEID","PATHS"],
                    "flags":["aclk"]
                },{
                    "hostname":"costa-desktop",
                    "host_id":"25d148e4-603c-11ed-b52e-d85ed30ec5e6",
                    "node_id":"e0ff25b3-67d2-4259-8767-8118de3a34eb",
                    "claim_id":"6b3d255d-6660-4b06-912d-e4f424c65096",
                    "hops":1,
                    "since":1730806842,
                    "first_time_t":1730580991,
                    "start_time":1931,
                    "shutdown_time":11913,
                    "capabilities":["V1","V2","VN","VCAPS","HLABELS","CLAIM","CLABELS","LZ4","FUNCTIONS","REPLICATION","BINARY","INTERPOLATED","IEEE754","ML","DYNCFG","SLOTS","ZSTD","GZIP","BROTLI","PROGRESS","NODEID","PATHS"],
                    "flags":["aclk"]
                },{
                    "hostname":"plaka-parent",
                    "host_id":"7105e19c-ddbc-11ec-944e-324165a44248",
                    "node_id":"796de1e5-74f8-4501-a4b7-f59eafa43a2b",
                    "claim_id":"7105e19c-ddbc-11ec-944e-324165a44248",
                    "hops":2,
                    "since":1730806843,
                    "first_time_t":1730581020,
                    "start_time":2622,
                    "shutdown_time":8669,
                    "capabilities":["V1","V2","VN","VCAPS","HLABELS","CLAIM","CLABELS","LZ4","FUNCTIONS","REPLICATION","BINARY","INTERPOLATED","IEEE754","ML","DYNCFG","SLOTS","ZSTD","GZIP","PROGRESS","NODEID","PATHS"],
                    "flags":["aclk"]
                }]

The fields are as follows:

1. hostname: the node name of the node that replicates the node
2. host_id, node_id, claim_id are the machine guid, the node id and the agent claim id of the agent
3. hops: defines the distance of the node from the origin (0 = the origin agent)
4. since: is the epoch timestamp since this connected
5. first_time_t: is the oldest timestamp in the database the agent maintains
6. start_time: is the median time in ms the agent needs to start
7. shutdown_time: is the median time in ms the agent needs to shutdown
8. capabilities: is the streaming capabilities on this connection
9. flacks: if it contains aclk, then this agent is connected to cloud

This is translated to something like this:

flowchart TD
subgraph s1[" "]
    A("<b>manjaro</b>
        <small>Origin Server
        Rentetion: 2d5h</small>")
    B("<b>costa-desktop</b>
        <small>Hops: 1
        Rentetion: 1y</small>")
    C("<b>plaka-parent</b>
        <small>Hops: 2
        Rentetion: 2y</small>")
end

A ==> B
B ==> C

NC("Netdata Cloud") -.-> A
NC -.-> B
NC -.-> C

On hover of each node we could get a additional information about the node.

Description

As above.

Importance

nice to have

Value proposition

1. Let users see the replication of their systems.

Proposed implementation

As above.
