Weaviate: Change DOCUMENTID type to text and tokenization to keyword

[hsm207]

Initial Checks

• I have searched Google & GitHub for similar requests and couldn't find anything
• I have read and followed the docs and still think this feature is missing

Description

The string data type is deprecated in weaviate 1.19 so we need to update the type of DOCUMENTID to text.

The default tokenization for a text data type is word. This should be changed to keyword to be consistent with the behaviour when DOCUMENTID's data type was string.

Affected Components

• Vector Database / Index
• Representing
• Sending
• storing
• multi modal data type
