Unable to catch any connection error

[copbint]

Versions

• etcd: v3.4.15
• jetcd: 0.7.1
• java: jdk1.8.0_212

Describe the bug When connection error happened(connection refused/ssl handleshake failuer...), jetcd will try to reconnect in infinite, and there is never any Exception throw out, so it is unable to know what is wrong.

To Reproduce

1. run a etcd server : (certs are all in the reproduce example)

etcd-v3.4.15-windows-amd64/etcd.exe --cert-file etcd.cer  --key-file  etcd-pkcs8.pem  --trusted-ca-file  ca.cer --client-cert-auth   --listen-client-urls  'https://127.0.0.1:2379'   --advertise-client-urls 'https://127.0.0.1:2379'

2. run the reproduce example Application

3. uncoment this line, and the exampel works well

Are you able to digg into the issue a little bit more ?

[copbint]

I have debugged the code a lot, but the async code in future/promise is just so complicated for me.
