createToken missing explicit_max_ttl and renewable options

[msbit01]

https://www.vaultproject.io/docs/auth/token.html#post includes options for an explicit_max_ttl and whether or not the token should be renewable. v3.0.0 of the vault-java-driver does not support these options. It would be great if these could be added.

Acceptance Criteria:
java-vault-driver should support all options for createToken

Suggested Tech Steps:
Update Auth.TokenRequest (

vault-java-driver/src/main/java/com/bettercloud/vault/api/Auth.java

Line 38 in 2e00c2f

public static class TokenRequest implements Serializable {

) to take these parameters.

There is one more essential option "entity-alias" is also missing. I would make a PR to implement those. Please let me know if there are any concerns.

Thanks,
