Create StateRecoveryDB and MessageRecoveryDB classes

[ishantiw]

Description

• Propose and define types for each data type, define getDBInstance to create DB instance. Below is one proposal,

// Data to be stored for state recovery
interface InclusionProof {
    height: number;
    stateRoot: Buffer;
    inclusionProof: OutboxRootWitness & { key: Buffer; value: Buffer };
    storeValue: Buffer;
    storeKey: Buffer;
}

interface ProofByHeight {
  Proof: Proof;
  Height: number
}

// Data to be stored for message recovery
interface CCMAndInclusionProofByHeight {
  ccms: CCM[];
  Proof: Proof;
  Height: number;
}

• Define DB classes for state and message recovery without implementation

  
  class StateRecoveryDB {
  // Save proof by height
  public setInclusionProof(chainID, queryKey, proofByHeight) {}
  public getInclusionProof(chainID, queryKey) {}
    public getInclusionProofByHeight(height: number) {}
    public deleteInclusionProofsUntilHeight(height: number) {}
  }

class MessageRecoveryDB { // Save CCMs and proof by height public setCCMs(chainID, CCMAndInclusionProofByHeight[]) {} public getCCMs(chainID) {} }

### Acceptance Criteria

- Should have all the files, interfaces and tests should be present
