chore: upgrade to golang-jwt 3.2.1 to fix CVE-2020-26160

CVE-2020-26160[0] is an access restriction bypass under certain
circumstances when validating audience checks. The original
dgrijalva/jwt-go project is no longer maintained[1] and will not be
issuing a fix for this CVE[2]. Instead, they have transferred ownership
to golang-jwt/jwt[2][3][4].

The following was performed:

1. update chronograf and jsonweb to import golang-jwt/jwt
2. go mod edit -require github.com/golang-jwt/[email protected]+incompatible
3. go mod edit -droprequire github.com/dgrijalva/jwt-go
4. go mod tidy
5. make
6. make test
