ES error: Limit of total fields [1000] has been exceeded

[abitmore]

Bug Description

The develop branch is unable to sync if the es_objects plugin is enabled. Error message:

{"index":{"_index":"objects-proposal","_type":"_doc","_id":"1.10.69039","status":400,"error":{"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"illegal_argument_exception","reason":"Limit of total fields [1000] has been exceeded while adding new fields [11]"}}}}

It occurs on block 66225581. The operation that creates the proposal 1.10.69039 was

[22,{"fee":{"amount":991139,"asset_id":"1.3.0"},"fee_paying_account":"1.2.605792","expiration_time":"2022-02-18T07:32:57","proposed_ops":[{"op":[69,{"fee":{"amount":52501,"asset_id":"1.3.0"},"owner_account":"1.2.1802985","asset_type":"1.3.5883","balance":"10000000000","fee_rate":0,"max_duration_seconds":604800,"min_deal_amount":1000000,"enabled":true,"auto_disable_time":"2022-05-12T07:32:31","acceptable_collateral":[["1.3.5286",{"base":{"amount":1,"asset_id":"1.3.5883"},"quote":{"amount":10,"asset_id":"1.3.5286"}}],["1.3.5589",{"base":{"amount":1,"asset_id":"1.3.5883"},"quote":{"amount":1,"asset_id":"1.3.5589"}}]],"acceptable_borrowers":[],"extensions":[]}]}],"extensions":[]}]

According to ES docs(https://www.elastic.co/guide/en/elasticsearch/reference/7.17/mapping-settings-limit.html), the setting can be updated if really required,

index.mapping.total_fields.limit - The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The default value is 1000.
