tier/glusterd : making new tier detach command throw warning
For detach tier, the validation was done using the string "detach-tier" but the new commands used has the string "tier". Making the string use "tier" to compare, creates problem as the tier status and tier detach have the keyword "tier". So tier detach and tier status were separated. and strtok was used to prevent the condition from passing when the volume name has a substring of "tier". (only the second word from the string is got and checked if the feature is tier) Problem: new detach tier command doesnt throw warnings like "not a tier volume" or " detach tier not started" respectively instead it prints empty output. Fix: while validate the volume is checked if its a tiered volume if yes it is checked if the detach tier is started, else a warning is thrown respectively.
