[Backup Service] 'Communication error' when trying to create a repository.

Description

I have observed the following error a few times (on older builds as well), however I cannot determine if this is a user error or bug in the service. Once the issue triggers you can observe it happening repeatedly.

Could not add repository: location not accessible by all nodes - node db0e41a2f032717e636a90e37b8aacaa cannot access location /tmp/entbackup_10.112.210.101: rpc error: code = Unavailable desc = connection error: desc = "transport: authentication handshake failed: x509: certificate is valid for 127.0.0.1, not 10.112.210.101"

Additional commentary:

I cannot provide the steps to reproduce the issue. But here's a general idea of the steps I took today.

1. Used vagrant to create VMs with couchbase-server 7.0.0-3435.

2. During one of the two tests I was writing today, I provisioned 3 nodes into a cluster which succeeded and attempted to add a repository which failed.

The shared directory is working as intended, the shared directory has been succesfully shared between all of the clients.
