do not use sudo for local fetch ucp task

[vvb]

• ansible has issues while mixing up local_action and root access.
• Fix for ucp | create a local fetch directory if it doesn't exist - errors out. #79
• For this fix itself to work we need ansible 2.0.

LGTM

[mapuri]

thinking more, may be we should add a task that checks/validates that the ansible control machine is running ansible v2.0. WDYT?

We can track that as a separate issue may be.

[vvb]

@mapuri yes, I will add the check.

[mapuri]

@vvb, is this ready for merge?

Were you planning to add ansible version check as part of this? I have filed #87 to perform some checks, may be we can address it as part of that PR.

[vvb]

@mapuri that sounds better. so, this is good to merge then.
