Allow 'alter column' operations to include multiple sub-operations. This
means migrations like this one are now possible:
```json
{
"name": "35_alter_column_multiple",
"operations": [
{
"alter_column": {
"table": "events",
"column": "name",
"name": "event_name",
"type": "text",
"nullable": false,
"unique": {
"name": "events_event_name_unique"
},
"check": {
"name": "event_name_length",
"constraint": "length(name) > 3"
},
"up": "(SELECT CASE WHEN name IS NULL THEN 'placeholder' ELSE name END)",
"down": "name"
}
}
]
}
```
This 'alter column' operation:
* Renames a column
* Changes its type
* Sets it `NOT NULL`
* Adds a unique constraint
* Adds a check constraint
Previously, this would have required 5 different operations.
