the class EIPManager method bindEIP.

/**
 * Checks if an EIP is bound and optionally binds the EIP.
 *
 * The list of EIPs are arranged with the EIPs allocated in the zone first
 * followed by other EIPs.
 *
 * If an EIP is already bound to this instance this method simply returns. Otherwise, this method tries to find
 * an unused EIP based on information from AWS. If it cannot find any unused EIP this method, it will be retried
 * for a specified interval.
 *
 * One of the following scenarios can happen here :
 *
 *  1) If the instance is already bound to an EIP as deemed by AWS, no action is taken.
 *  2) If an EIP is already bound to another instance as deemed by AWS, that EIP is skipped.
 *  3) If an EIP is not already bound to an instance and if this instance is not bound to an EIP, then
 *     the EIP is bound to this instance.
