Make plugin startup timeout configurable

[nmische]

Is your feature request related to a problem? Please describe. I'm always frustrated when I attempt to run steampipe with a large number of kubernetes connections, as I get the following error:

Error: failed to start plugin manager: timeout while waiting for plugin to start

Describe the solution you'd like Make plugin startup timeout configurable. See: https://github.com/turbot/steampipe/blob/develop/pkg/pluginmanager_service/plugin_manager.go#L672-L673

Describe alternatives you've considered

• Run a local build of steampipe with the hardcoded timeout updated.
• Shell script to dynamically enable groups of kubernetes connections in my steampipe config.

Additional context I have tried to figure out how to add this configuration option a few times but have yet to have any success.

I finally fingured out what I was doing wrong while trying to develop a fix for this issue. I needed to rebuild the fdw to pick up the changes to the plugin HCL.
