Kefu Chai d1c222d9bd config: specialize config_from_string() for sstring ...

Specialize config_from_string() for sstring to resolve lexical_cast
stream state parsing limitation. This enables correct handling of empty
string configurations, such as setting an empty value in CQL:

```cql
UPDATE system.config SET value='' WHERE
name='allowed_repair_based_node_ops';
```
Previous implementation using boost::lexical_cast would fail due to
EOF stream state, incorrectly rejecting valid empty string conversions.
