Description:
1. New enum value MYSQL_OPT_TLS_VERSION is not added at the end.

2. Changes related to --tls_version variable bumped libmysqlclient version from 20.0.9 to 20.1.0.
This caused incompatibility between 5.7.9 and 5.7.10 because all existing symbols now have new symbol version.

How to repeat:
Check libmysqlclient version in 5.7.10.

Suggested fix:
1. Move MYSQL_OPT_TLS_VERSION to the end of enum.
2. For existing symbols, change symbol versions to old value of 20.0.9
