There is a discrepancy between 015 and 026 versions:

015:
after creating fabric, the ssh session is recreated (multiple times) during provision of fabric - this leads to a need to reconnect the ssh client multiple times.. after the fabric is provisioned, everything is working OK

026:
after executing fabric:create, the ssh session is not recreated anymore, what leads to an error when creating (for example, I believe this error will be with more commands) child-container:

container-create-child root test
The following containers have failed:
	test: java.lang.SecurityException: Authentication failed

I was unable to reproduce it manually using bin/client, but this issue will cause problems in our automated test suite.

I'm attaching a reproducer, please see the steps to reproduce.

What the reproducer does is:
015:

• connect client
• fabric:create --wait-for-provisioning
• the ssh session will be recreated - the test will catch an exception, wait for 120 seconds and reconnect again
• container-create-child root test
• container will be created

026:

• connect client
• fabric:create --wait-for-provisioning
• the session WILL NOT be recreated - so everything is fine
• container-create-child root test
• container WILL NOT be created - Authentication failed
