Add bootstrap check for disabling agent when required

[eyalkoren]

What does this PR do?

• allow to disable JVM bootstrap checks with ELASTIC_APM_DISABLE_BOOTSTRAP_CHECKS environment variable, this is currently only possible with -Delastic.apm.disable_bootstrap_checks JVM argument (using JVM system properties), hence allowing to disable bootstrap checks when JVM arguments modification is not possible.
• ensure that JVM tools detection issues an error and prevents the agent to start.
• provide an additional way to exclude some processes from instrumentation by relying on JVM system properties.

Checklist

[question] Does the patterns are matched against the whole JVM command line or only the main class and the system properties ?

[eyalkoren]

There is an explanation above for the allow list and in the table.
Is it not clear from those what is used in each?
As for the allowlist - it is only the main class or jar and JVM parameters, basically the contents of the sun.java.command system property. I will add this info. Let me know if anything else is required

[eyalkoren]

@SylvainJuge I removed the default exclude list, as it doesn't seem required at this point.
Please only review that and the added documentation. Thanks!
