- Enhances the Host connecting logic to avoid connecting storm (where Agent opens multiple sockets against Management Server).
- Implements HostConnectProcess task where Host upon connection checks whether lock is available, traces Host connecting progress, status and timeout.
- Introduces AgentConnectStatusCommand, where Host checks whether lock for the Host is available (i.e. "previous" connect process is finished).
- Implementes logic to check whether Management Server has lock against Host (exposed MySQL DB lock presence via API)
- Removes synchronization on Host disconnect process, double-disconnect logic in clustered Management Server environment, added early removal from ping map (in case of combination ping timeout delay + synchronized disconnect process the Agent Manager submits more disconnect requests)
- Introduces parameterized connection and status check timeouts
- Implements backoff algorithm abstraction - can be used either constant backoff timeout or exponential with jitter to wait between connection Host attempts to Management Server
- Implements ServerAttache to be used on the Agent side of communication (similar to Attache on Management Server side)
- Enhances/Adds logs significantly to Host Agent and Agent Manager logic to trace Host connecting and disconnecting process, including ids, names, context UUIDs and timings (how much time took overall initialization/deinitialization)
- Adds logs to communication between Management Servers (PDU requests)
- Adds DB indexes to improve search performance, uses IDEMPOTENT_ADD_INDEX for safer DB schema updates

This PR aligns the use of terminology, renaming VM / virtual machine references to 'Instance' and also capitalising the terms Templates, Network, Snapshot, User, Account in CloudStack APIs, error and log messages, events, tooltips, etc. Many typos, grammar and spelling mistakes were fixed, also terms like IPv4, VPN, VPC, etc. were properly capitalised. Some error messages were cleaned for better readability. The test cases, expecting some exception strings were adjusted accordingly.
Here is the wiki page, describing the changes in details:
