Current scheme requires people to calculate exact percentages for their
nodes. People are bad with pecentage calculations and it's really inconvenient
if you have more than 3-4 nodes. What I'd like to have is ability to specify
weights like weights, not percentages:
.._0_WEIGHT=3
.._1_WEIGHT=1
.._2_WEIGHT=1
and let the gateway calculate things for me.
After discussion, we decided to simplify attribute translation for now. Full translation requires support for UTF-8 values encoded according to RFC 8187/7230, this can be clarified and implemented in further PRs.
1. Remove translation tables
2. Use simple translation rules only, for now ignoring UTF-8 keys and values
- `X-Attribute-NEOFS-` prefixed headers considered well-known system attributes
- System Attribute key is uppercased
- System Attribute key's `-` translates to `_`
- `X-Attribute-` prefixed headers considered regular object attributes
- Normal attribute key is a result of http header prefix trimming
- Value string should be left as is, for now
```
HTTP:
X-Attribute-NEOFS-Expiration-Epoch: 123
X-Attribute-FileName: cat.jpg
NeoFS:
__NEOFS__EXPIRATION_EPOCH: "123"
FileName: "cat.jpg"
```

- Maybe it could be rephrased to "attribute name prefixed with X-Attribute-"
- Maybe it worth renaming to userAttributeHeaderPrefix
- Requirement for having only one file uploaded at a time has to be reflected in documentation.
- Maybe this should be reflected in doc
- I'm not sure if missing timestamp attribute should be forced on gateway level. Normally it should be set by app and there should be a way not to set it.
