Introduce downsampling configuration for data stream lifecycle (#97041)

Browse source 
This PR introduces downsampling configuration to the data stream lifecycle. Keep in mind downsampling implementation will come in a follow up PR. Configuration looks like this:
```
{
  "lifecycle": {
    "data_retention": "90d",
    "downsampling": [
      {
        "after": "1d",
        "fixed_interval": "2h"
      },
      { "after": "15d", "fixed_interval": "1d" },
      { "after": "30d", "fixed_interval": "1w" }
    ]
  }
}
```
We will also support using `null` to unset downsampling configuration during template composition:
```
{
  "lifecycle": {
    "data_retention": "90d",
    "downsampling": null
  }
}
```
