Add timeout option for command line when running a vcert playbook

[madamorr]

BUSINESS PROBLEM
When using the playbook functionality of vcert, we sometimes have times where certificate issuance takes longer than the default timeout.

PROPOSED SOLUTION
Add a --timeout to the command line when using run for playbooks.

CURRENT ALTERNATIVES
None as we have to retry multiple times before we receive the issued certificate.

VENAFI EXPERIENCE
I have been utilizing vcert for a year to automate the certificate lifecycle for our organization. We heavily rely on vcert for certificate management on a daily basis.

The timeout is happening before vcert playbook enters the retrieval loop.
I see the following line in the --debug output:
"successfully updated Request with zone config values"

So I know the timeout is happening before the polling since I do not see Debug statement "successfully requested certificate" when the timeout occurs.

2026-05-06T10:30:16.405-0500 DEBUG vcertutil/vcertutil.go:63 successfully updated Request with zone config values
2026-05-06T10:30:26.872-0500 ERROR vcert/playbook.go:151 error running task {"task": "myserver510", "error": "error requesting certificate myserver510: Unexpected status code on TPP Certificate Request.\n Status:\n 500 Server Error. \n Body:\n {\n "error": "HTTP POST on resource 'https://venafi-ttp-server.com:443/vedsdk/certificates/request' failed: Timeout exceeded.",\n "errorDetails": null\n}\n"

A longer timeout for "reqID, reqErr := client.RequestCertificate(&vRequest)" would be necessary.

I found the timeout for playbooks in the code. The timeout setting is not documented.
