fix: changes required for migrate dev to main

[jiacai2050]

Rationale

When rename ceresdb to horaedb, there are some breaking changes.

In order to allow old version to upgrade to main branch, some changes are required.

Detailed Changes

• Make default catalog configurable via env vars,

Test Plan

Manually.

Before upgrade, first setup required envs

export HORAEDB_DEFAULT_CATALOG=ceresdb

Etcd's root should be configured both in horaedb and horaemeta

For horaedb

[cluster_deployment.etcd_client]
server_addrs = ['127.0.0.1:2379']
root_path = "/rootPath"

For horaemeta

storage-root-path = "/rootPath"

Then

1. Upgrade horaemeta, then horaedb will throw following errors, which is expected

2024-01-23 14:37:57.726 ERRO [src/cluster/src/cluster_impl.rs:136] Send heartbeat to meta failed, err:Failed to send heartbeat, cluster:defaultCluster, err:status: Unimplemented, message: "unknown service meta_service.MetaRpcService", details: [], metadata: MetadataMap { headers: {"content-type": "application/grpc"} }

2. Upgrade horaedb, after all server upgraded, the cluster should be ready for read/write, and old data could be queried like before.
