Introduce an optimised way of reading a graph of data from the webclient.
Before this commit:
When reading data from the webclient it could at most read multiple ids of the same model in one RPC.
This mean that when reading x2many or specific information on many2one, that could only be done after the initial read (when the client knows the ids of the comodels) and model by model.
After this commit:
Introduce methods web_read and web_search_read_unity. Both method receive a specificiation for the fields instead of a list of fields. The specification can request fields from the model, as well as follow relations and request fields for each relations, recursively.
Example of web_read specification for account_move
```python
{'name': {}},
{'date': {}},
{'journal_id': {'fields': {'display_name':{}}}
},
...
{'invoice_line_ids' :
{
'fields': {
'journal_id' : {'fields': {'display_name:{}}},
'move_name' : {},
...
'tax_ids' : {
fields: {
'display_name':{},
...
}
}
}
}
}
```
Result for this example with 2 invoice lines
```python
{
'id': 1234,
'name' : 'invoice name ABC',
'journal_id: {
'id': 999,
'display_name': 'Customer Invoices'
},
...
'invoice_line_ids': [
{
'id': 666,
'journal_id': {
'id': 999,
'display_name': 'Customer Invoices'
},
'move_name': 'a move name',
'tax_ids': [
{
'id': 333,
'display_name: "15% tax",
...
}
]
},
{
'id': 667,
'journal_id': {
'id': 999,
'display_name': 'Customer Invoices'
},
'move_name': 'another move name',
'tax_ids': [
{
'id': 334,
'display_name: "21% customer tax",
...
}
]
}
]
}
```
