Issue #243 Show if Cluster Capacity is Reached

[kishansagathiya]

Idler would be giving 503 if Cluster Tenant Resource Capacity is Reached. Modified Unidle function to handle that

Now waiting template will show the message "Cluster Tenant resource capacity for current cluster is full, please wait...", if Cluster Capacity is reached

243

@sthaha @containscafeine What would be really nice for this is some UI magic such that the message that we see while jenkins is unidling changes dynamically i.e., If the ajax request that the page sent to proxy gives 503 change the message to Cluster Tenant resource capacity for current cluster is full, please wait... and if it gives 202 it should change to Jenkins has been idled. It is starting now, please wait...

WDYT?
