Support create token with headers

[coderzc]

Master Issue: #

Motivation

Currently, the tool that generates the token cannot attach headers. We should support it. For example, it makes sense to attach a kid field for JWKS.

What's the difference between this and the method in the https://github.com/streamnative/pulsarctl/pull/1455/files#diff-c61908f43ade6604eaae204d799b4b61f0ea0f98df937b11b8d8caacc73df0b0R45?

Seems we already support the API with header:

pulsarctl/pkg/cmdutils/token.go

Line 94 in 79b2d46

func (t *token) CreateToken(

what’s the difference between them? Maybe we can use the existing API to extend more options for the jwt claims?

The CreateToken method must be with claims and Create will call CreateToken, I only pass headers params from Create to CreateToken

pulsarctl/pkg/cmdutils/token.go

Lines 76 to 92 in 79b2d46

	func (t *token) Create(algorithm algorithm.Algorithm, signKey interface{}, subject string,
	expireTime int64) (string, error) {
	var claims *jwt.MapClaims
	if expireTime <= 0 {
	claims = &jwt.MapClaims{
	"sub": subject,
	}
	} else {
	claims = &jwt.MapClaims{
	"sub": subject,
	"exp": jwt.NewNumericDate(time.Unix(expireTime, 0)),
	}
	}
	return t.CreateToken(algorithm, signKey, claims, nil)
	}

@zymap I let cmd call the CreateToken method and revert the modifications to Create, PTAL

There is a method set.StringToStringVar() to receive a map value from the command line. We can use that instead of parse the map value by ourselves.

Good idea, updated.
