Offline error report storage and auto re-submission
- BacktraceDatabase - offline error report storage and auto re-submission support in the event of network outage and server unavailability.
- BacktraceClient.Send now works properly with TLS 1.2 under .NET 4.6+ and .NET Core 2.0. However, BacktraceClient.SendAsync is strongly recommended whenever possible.
- Removed TlsLegacySupport flag in BacktraceClient
