Fix Manage API synchronous call

RPCAPI call to Scheduler to perform share_type and host
validation should be asynchronous so share can be
created in DB with status "manage_error" if validation
is not successful.

This change also addresses incorrect exception type in API
and DB popping fields from supplied parameter.
