chore(daemon): removing password, entropy and validator number as prompt, and adding flags instead

[kehiy]

Description

In this PR I removed the validator number, password, and entropy as prompt and hard-coded values. now we get them as flags from the user, this helps other interfaces and clients like GUI use this init command with ease.

After looking at all flags I suggest change the text to this:

workingDirOpt := initCmd.Flags().StringP("working-dir", "w",
		cmd.PactusDefaultHomeDir(), "the path to the working directory to save the wallet and node files")

	testnetOpt := initCmd.Flags().Bool("testnet",
		true, "initialize working directory for joining the testnet") // TODO: make it false after mainnet launch

	localnetOpt := initCmd.Flags().Bool("localnet",
		false, "initialize working directory for localnet for developers")

	restoreOpt := initCmd.Flags().String("restore",
		"", "restore the 'default_wallet' using a mnemonic or seed phrase")

	passwordOpt := initCmd.Flags().StringP("password", "p",
		"", "the wallet password")

	entropyOpt := initCmd.Flags().IntP("entropy", "e",
		128, "entropy bits for seed generation. range: 128 to 256")

	valNumOpt := initCmd.Flags().Int("val-num",
		0, "number of validators to be created. range: 1 to 32")
		```
		
Note: 
- all messages start with lowercase
- No default in the help string (Cobra adds default)
- Add range for flags that accepts range
- No parentheses "()" in help message

@b00f fixed.
should we also do the same checks for passwordOpt?
