[IMP] util.explode_query_range: replace problematic parallel_filter…

… formatting

The usage of `str.format` to inject the parallel filter used to explode queries is not
robust to the presence of other curly braces. Examples:

1. `JSON` strings (typically to leverage their mapping capabilities):

see 79f3d71, where a query had to be modified to
accomodate that.

2. Hardcoded sets of curly braces:

```python
>>> "UPDATE t SET c = '{usage as literal characters}' WHERE {parallel_filter}".format(parallel_filter="…")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'usage as literal characters'
```

Which can be (unelegantly) solved adding even more braces, leveraging one side-effect of
`.format`:

```python
>>> "UPDATE t SET c = '{{usage as literal characters}}' WHERE {parallel_filter}".format(parallel_filter="…")
"UPDATE t SET c = '{usage as literal characters}' WHERE …"
```

3. Hardcoded curly braces (AFAICT no way to solve this):

```python
>>> "UPDATE t SET c = 'this is an open curly brace = {' WHERE {parallel_filter}".format(parallel_filter="…")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: unexpected '{' in field name
```

```python
>>> "UPDATE t SET c = 'this is a close brace = }' WHERE {parallel_filter}".format(parallel_filter="…")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: Single '}' encountered in format string
```

In order to adapt to this commit, some queries had to be updated.
