Describe the feature you'd like:

Hi, some naming are inconsistent, such as

• db VS tidb
• kv VS tikv
• cdc VS ticdc
• ...

eg:

(base) root@rabbit:tiup <master(v1.1.0-40-gab2232a)>$ ./bin/tiup-playground -h
Bootstrap a TiDB cluster in your local host, the latest release version will be chosen
if you don't specified a version.

Examples:
  $ tiup playground nightly                         # Start a TiDB nightly version local cluster
  $ tiup playground v3.0.10 --db 3 --pd 3 --kv 3    # Start a local cluster with 10 nodes
  $ tiup playground nightly --monitor=false         # Start a local cluster and disable monitor system
  $ tiup playground --pd.config ~/config/pd.toml    # Start a local cluster with specified configuration file,
  $ tiup playground --db.binpath /xx/tidb-server    # Start a local cluster with component binary path

Usage:
  tiup playground [version] [flags]
  tiup [command]

Available Commands:
  display
  help        Help about any command
  scale-in
  scale-out

Flags:
      --db int                   TiDB instance number (default 1)
      --db.binpath string        TiDB instance binary path
      --db.config string         TiDB instance configuration file
      --db.host host             Playground TiDB host. If not provided, TiDB will still use host flag as its host
      --drainer int              Drainer instance number
      --drainer.binpath string   Drainer instance binary path
      --drainer.config string    Drainer instance configuration file
  -h, --help                     help for tiup
      --host string              Playground cluster host (default "127.0.0.1")
