Invalidate existing enclave session during connection (re)connect

[machavan]

Description:

For AE with secure enclave, the driver connections receives an error 33195 - Internal enclave error. Enclave was provided with an invalid session handle. For more information, contact Customer Support Services, post failovers ( in case of Always On setup).

This could be happening because of driver using existing enclave session from the enclaveCache in the driver.

This fix invalidates the existing enclave session as part of the connect method.
