Description of problem:
When I used remote package install/update/remove, the operation is synchronized by default. But When I try to use errata apply, the operation is asynchronous - hammer doesn't wait for pending status is changed.

This behaviour is inconsistent.

>>  hammer --server <SERVER> --username <USER> --password <PASS> content-host errata apply -h

Usage:
    hammer content-host package install [OPTIONS]

Options:
    --async                       Do not wait for the task
    --content-host CONTENT_HOST_NAME Name to search by
    --content-host-id CONTENT_HOST_ID UUID of the content host
    --organization ORGANIZATION_NAME Organization name to search by
    --organization-id ORGANIZATION_ID  
    --organization-label ORGANIZATION_LABEL Organization label to search by
    --packages PACKAGES           List of package names
                                  Comma separated list of values.
    -h, --help                    print help


>> hammer --server <SERVER> --username <USER> --password <PASS> content-host errata apply -h

Usage:
    hammer content-host errata apply [OPTIONS]

Options:
    --content-host CONTENT_HOST_NAME Name to search by
    --content-host-id CONTENT_HOST_ID UUID of the content host
    --errata-ids ERRATA_IDS       List of Errata ids to install
                                  Comma separated list of values.
    --organization ORGANIZATION_NAME Organization name to search by
    --organization-id ORGANIZATION_ID  
    --organization-label ORGANIZATION_LABEL Organization label to search by
    -h, --help                    print help

Version-Release number of selected component (if applicable):
rubygem-hammer_cli_foreman_tasks-0.0.3-3.el6sat.noarch

How reproducible:
always

Steps to Reproduce:
1. register system
2. try to remote apply errata
3. check installed package from errata on system

Actual results:
1) operation is asynchronous by default
2) lost synchronize operation 

Expected results:
1) operation is synchronize by default
2) I can use --async flag for asynchronous operation
