Original GitHub issue: https://github.com/lldap/lldap/issues/1336

Motivation
User attribute values are stored as blobs and do not support substring matching in search filter, although attribute type is already known and stored in another table.

Describe the solution you'd like
Add a user_attribute_value_text column in user_attributes table. Fill in the text value when attribute has String type.
Implement AttributeSubtring search filter and query for String attributes.

Describe alternatives you've considered

Additional context
The issue is mentioned in #705.
With the additional text column, search on string attributes can also be case-insensitive #999
