Serialize and validate according to `ServiceProviderConfig`

[azmeuk]

Passing ServiceProviderConfig to the serialization and validation context would allow to check for additional things.

For example:

• if etag is not supported, then requests can avoid setting etags metadata
• if filter or sort are not supported, then they should not be passed when building SearchRequest objects.
• if bulk.maxOperation and bulk.mayPayloadSize are set, avoid to go beyond those limits when building a request
• I am not sure what to do with changePassword though
