[WindzCUHK]

Description

TODO

1. [x] update config yaml to v2.0.0
2. [x] update go.mod (depends on: https://github.com/yahoojapan/athenz-authorizer/pull/69)

changes

1. fix multiple naming consistency problem in config.go.
2. remove role token force enable
3. config version to v2.0.0
4. move unit test data to /test/data
5. add log level support
6. fix lint: SA1019: t.BuildNameToCertificate is deprecated: NameToCertificate only allows associating a single certificate with a given name. Leave that field nil to let the library select the first compatible chain from Certificates. (staticcheck)
7. handle timeout and ca in config.Athenz

@WindzCUHK (Perhaps out of the scope of this ticket, but) It's better to add a filed to allow configuration to change from Authorization: Bearer like other headers.(Although using another header name than Authorization: Bearer is against the standard.) https://github.com/yahoojapan/authorization-proxy/blob/745655002bae0ca52b8ab8a0d937691332019aff/config/config.go#L214-L233
