V1.3.1 Release

[dljvette]

Issue #, if available: #272, #273

Description of changes: Releasing changes for the following commits:

• Fixed: 1.3.0 issue that prevented on-premises instances from starting.
• ~Fixed~ See note below: Issue that prevented Windows clients from communicating with VPC endpoints (AWS PrivateLink).
• Fixed: Removed an expired certificate that was no longer used.
• Fixed: Removed the prompt message from the agent uninstall script used by AWS Systems Manager, making it easier to downgrade a host or fleet to a previous version of the agent.

Note on Windows VPC endpoint support This change includes a fix needed to address #272. However, due to a bug in how the resulting MSI is packaged, the patch was not picked up in the 1.3.1 public release. That will be expressed in the next release when established.
