Activate clang-tidy warning "readability-container-contains" 
This check suggests replacing <Container>.count() by
<Container>.contains() which is more speaking and in case of
multimaps/multisets also faster.

6fbb9f5e87 Implement EXPLAIN TABLE OVERRIDE for pre-validating overrides. 
Example:

```sql
EXPLAIN TABLE OVERRIDE mysql('127.0.0.1:3306', 'db', 'table', 'user', 'pw')
    PARTITION BY tuple(toYYYYMM(created), id % 8)
```

Validations done:

 * check that storage overrides do not reference unknown or nullable columns
 * check that default specifier is not modified for columns

1cc70ad524 Remove the possibility of adding columns with table overrides 
(except ALIAS columns)

Supporting this properly requires more comprehensive changes.
