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

sad:(
It's because that we need replace the keyword test-cluster to the real cluster name (the grafana template use test-cluster as the default one), and your cluster name contains the keyword test-cluster.

tiup/pkg/cluster/spec/grafana.go

Line 200 in 4f84a3f

`find %s -type f -exec sed -i "s/test-cluster/%s/g" {} \;`,

[lucklove]

We can add " in replace stage

The same issue in v.1.5 tiup. The cluster prefixed with test-cluster is a very common usage.
