Unable to reinitialize agent once shut downed

[GHkrishna]

What:

Reinitializing agent with await agent.initialize() after await agent.shutdown() gives an indyVdr error due to this implementation. Should we just return instead of throwing error:

public connect() {
    if (this._pool) {
      throw new IndyVdrError('Cannot connect to pool, already connected.')
    }

    this._pool = new PoolCreate({
      parameters: {
        transactions: this.config.genesisTransactions,
      },
    })
  }

This becomes,

public connect() {
    if (this._pool) {
      return
    }

    this._pool = new PoolCreate({
      parameters: {
        transactions: this.config.genesisTransactions,
      },
    })
  }

To reproduce

1. await agent.shutdown()
2. await agent.initialize()

I think the better approach would be to shutdown the pool at agent shutdown and remove the value initialization

[GHkrishna]

The issue for shutting down of pool still exists in IndyVDR. For now I think we can set the initialized value to null. And once it is resolved in VDR we can retro fit it. What do you think?

[TimoGlastra]

Yes i think that makes sense. But since we can't close it we should reuse the existing pool on initialize again
