It can be difficult to know what engines are available and where they come from. This could help with that.

### Describe the solution you'd like

```python
import xarray
xarray.list_engines()
```
Output:
```
Name | Description | Documentation

**Is your feature request related to a problem? Please describe.**
```python
import xarray

xds = xarray.DataArray([1], name=""a"", dims=""a"", attrs={""long_name"": ""Description about data""})
```
```python
xds.attrs
```
Output:
```
{'long_name': 'Description about data'}
```
```python
xds.to_dataframe().a.attrs
```
Output:
```
{}
```
**Describe the solution you'd like**
It would be nice if the attributes of the DataArray were preserved in each `pandas.Series` and the attributes of each `Dataset` were preserved on the `pandas.Dataframe`

**Additional context**

Things to be wary about is that it the pandas documentation says the `attrs` is experimental.
