Remove optional compile switch USE_SSL so that openssl is now an official kent repo dependency. Also using openssl sha1 in hgTracks multiregion. refs #17358.

 /* Calculate an openssl keyed-hash message authentication code (HMAC) */
 // You may use other openssl hash engines. e.g EVP_md5(), EVP_sha224,
 // EVP_sha512, etc
 // Be careful of the length of string with the choosen hash engine.
 // SHA1 needed 20 characters, MD5 needed 16 characters.
 // Change the length accordingly with your choosen hash engine
