Update user-guide - create VSAN storage policy command is incorrect

[ashahi1]

Sample command to create vsan policy is incorrect. Policy get created successfully but volume creation fails using that policy.

---

Current command in admin-cli.md:

/usr/lib/vmware/vmdkops/bin/vmdkops_admin.py policy create --name some-policy --content '(("proportionalCapacity" i0)("hostFailuresToTolerate" i0)'

If we use the above policy to create volume on vsan datastore - volume creation fails

root@sc-rdops-vm02-dhcp-52-237:~# docker volume create --driver=vsphere --name=MyVolume_2 -o size=10gb -o vsan-policy-name=some-policy
Error response from daemon: create MyVolume_2: VolumeDriver.Create: Failed to create volume MyVolume_2: error in line 2: syntax error
 VSAN_SPBMToVsanPolicy: Failed to convert SPBM string to VsanExpr: Not ready
Failed to set object policy : Input/output error 327684.
object setPolicy error: Failure

Correct command:

/usr/lib/vmware/vmdkops/bin/vmdkops_admin.py policy create --name some-policy-2 --content '(("proportionalCapacity" i0)("hostFailuresToTolerate" i0))'

Basically a closing parenthesis is missing at the end.

Can you please take care of it @ashahi1 ?
