Description

This PR adds a new parameter named registerExistingSFAKey in login function. If this param is set to true thn it sfa key will be imported to mpc.

Few things to consider:-

• Once sfa key is imported, key wont be accesible from sfa sdks.

• If you reset your MPC account, you cant access it from SFA again.

• Also this function will throw error if sfa key was generated for v1 sfa user. Upgrading for v1 users is not possible at all so we should mention this in docs such that application can handle this case while registering sfa user.

• This doesn't work for redirect flow, there is a bug in mpc core kit which doesn't handles redirect import case, so i have added it to throw an error if import key flow is used in redirect mode. We will remove the error once the redirect flow is fixed.

How has this been tested?

I have added one new test which creates a SFA key, than sets registerExistingSFAKey in mpc core kit so that mpc core kit import sfa key.
Later test tries to login with sfa again and sfa key should be empty, where as mpc exported key should match existing sfa key.

This PR affects, loginWithJwt, loginWithOauth and setupTkey functions
