CAMEL-19783: Added reconnection, even if a message has not yet been received

[jsight]

Description

This makes the following changes:

• Reconnect automatically with sensible defaults if we get an error before receiving the first message
• Expose an API for updating the initialReplayId. At first, this might sound silly. "initialReplayId" is effectively a constant, right? But there's a notable exception in cases where the client restarts the route dynamically and may pull a new replay id from another source. This can happen in the case of clustering, where only one route is active at a time and failover may occur.
• Expose an API to force plaintext via the consumer. This is for a similar reason to the existing method, but also makes it available to other test frameworks. We use a fake grpc endpoint to test the service and this will simplify that work.

Target

• [x ] I checked that the commit is targeting the correct branch (note that Camel 3 uses camel-3.x, whereas Camel 4 uses the main branch)

Tracking

• [ x] If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• [ x] I checked that each commit in the pull request has a meaningful subject line and body.

• [ x] I have run mvn clean install -DskipTests locally and I have committed all auto-generated changes
