Similar to #9969, but enabling job submitters to choose behavior at the jobspec level in task configuration.

pid_mode: "private" or "host" (optional)
ipc_mode: "private" or "host" (optional)

These would be applied per-task, configurable for exec and java tasks.

drivers/exec+java: Add task configuration to restore previous PID/IPC…
836ee9e 
… isolation behavior

This PR adds pid_mode and ipc_mode options to the exec and java task
driver config options. By default these will defer to the default_pid_mode
and default_ipc_mode agent plugin options created in #9969. Setting
these values to "host" mode disables isolation for the task. Doing so
is not recommended, but may be necessary to support legacy job configurations.

Closes #9970
