Grafana data source not found

Bug Report

Please answer these questions before submitting your issue. Thanks!

1. What did you do?

Deploy with the following yaml file:

global:
  user: "tidb"
  ssh_port: 22
  deploy_dir: "/tidb-deploy"
  data_dir: "/tidb-data"

pd_servers:
  - host: 127.0.0.1
    name: pd

tidb_servers:
  - host: 127.0.0.1

tikv_servers:
  - host: 127.0.0.1
    data_dir: "/mnt/test/tikv-data"

monitoring_servers:
  - host: 127.0.0.1

grafana_servers:
  - host: 127.0.0.1

Deploy with command: tiup cluster deploy toda-test-cluster v4.0.4 ./test-cluster.conf

Then visit http://127.0.0.1:3000/d/SVbh2xUWk/toda-test-cluster-tiflash-summary?orgId=1.

2. What did you expect to see?

No error in grafana.

3. What did you see instead?

I got an error: Datasource named toda-toda-test-cluster was not found. The datasource set in dashboard is toda-toda-test-cluster, but the real datasource name is toda-test-cluster

4. What version of TiUP are you using (tiup --version)?

v1.0.8 tiup
Go Version: go1.13
Git Branch: master
GitHash: 4276089

Start by running the reported tiup cluster deploy command with the supplied YAML, then open the Grafana dashboard URL and compare the configured datasource with the dashboard's requested name. Done means the dashboard loads without a datasource-not-found error and the datasource names agree.
