playground: support microservices mode

[rleungx]

What problem does this PR solve?

Introduce the pd-ms mode for better testing of the PD microservices mode.

Ref #2429

What is changed and how it works?

Usage:

tiup-playground nightly --pd.mode ms

It will start 1 API, 1 TSO, 1 resource manager server by default. If we want to start more, just use the following cmd like other mode:

tiup-playground nightly --pd.mode ms --pd.api 3 --pd.tso 2 --pd.rm 1

Output:

🎉 TiDB Playground Cluster is started, enjoy!

Connect TiDB:   mysql --comments --host 127.0.0.1 --port 4000 -u root

For tikv-slim:

tiup-playground nightly --mode tikv-slim --pd.mode ms --pd.api 3 --pd.tso 2 --pd.rm 1

Output:
