Description:

def create(cidr_block, instance_tenancy=None, vpc_name=None,
           enable_dns_support=None, enable_dns_hostnames=None, tags=None,
           region=None, key=None, keyid=None, profile=None):
    '''
    Given a valid CIDR block, create a VPC.

    An optional instance_tenancy argument can be provided. If provided, the
    valid values are 'default' or 'dedicated'

    An optional vpc_name argument can be provided.

    Returns {created: true} if the VPC was created and returns
    {created: False} if the VPC was not created.

    CLI Example:

    .. code-block:: bash

        salt myminion boto_vpc.create '10.0.0.0/24'
