commit d5c29e1be5ff12045c6dd324ca73509a5213adc3
Author: Jay Jahns <jjahns@xxxxxxxxxx>

    Add connection pool size to vSphere settings
    
    In larger environments, the default value of 10 for the HTTP connection
    pool is insufficient as Nova will begin to warn user that the pool
    is full and begin discarding connections.
    
    This change adds the ability to configure the connection_pool_size in
    Nova.  The default is 10 and the minimum value is also 10.
