Retry mounting daos container

[harshthakkar01]

daos_agent.sock file is not immediately available when we start the daos-agent process for ubuntu/ debian.

Failed to connect to /var/run/daos_agent/daos_agent.sock, errno=2(No such file or directory)

Retrying dfuse command works. Discussed with PS team, this is a race condition.
