Mercury is about to remove built-in Ckb Indexer RPCs

[EthanYuan]

CKB is currently embedding Ckb Indexer internally, and the upcoming CKB version will support all Ckb Indexer Rpcs. At that time, users will no longer need the original Ckb Indexer or Mercury's built-in indexer RPCs support.

Based on the above, after the new ckb version is released, Mercury will remove the indexer RPCs.

[EthanYuan]

ckb 0.105.0 has completed the merge of indexer, and Mercury's support for indexer can be removed.

steps to achieve：

• Remove all indexer-related rpcs' interfaces and related implementations
• Optimize the database layer
  • it is known that there is an additional dependency on this table “mercury_indexer_cell”, check if there is an alternative to the table
  • if it is possible, remove the table “mercury_indexer_cell”
