Heimdall metrics + Metrics HTTP server rationalization (#8094)
This is an update of:

https://github.com/ledgerwatch/erigon/pull/7846

which uses a local fork of victoria metrics to include the changes that
https://github.com/anshalshukla added to the original for we where
using.

It also includes code to address the duplicate metrics issue identified
here:

https://github.com/ledgerwatch/erigon/issues/8053

It has one more associated fix which is to correctly add a metadata
label to counters, these where previously labelled as gauges.

e.g. 

```
# TYPE p2p_peers counter
p2p_peers 0
```
rather than

```
# TYPE p2p_peers gauge
p2p_peers 0
```
