> This is refactor to Server Manager class from  HBASE-1017
> I separate it for reasons:
>  * Its better to have several small patchs and apply them iterativly then one great path
>  * I fu..**  tired from synchronising w/ SVN  (this class changes frequently), you can saw 10 patches in HBASE-1017
>  
> We need this refactoing for reasons:
>  *  Server Manager looks like shi**.. bad thing...
>  * is every time harder to make any chnages
>  * it is becoming more ugly every time........
> What changes are done:
> ServerManager has mapping:
>     * serverName 2 serverInfo,
>     * serverAddr 2 serverInfo,
>     * serverName 2 load,
>     * load 2 severName
> 1) serverName 2 load - not necessary if you have serverName 2 serverInfo
> 2) All mappings are encapsulated in ServersInfo class (inner class of ServerManager)
> 3) ServersInfo has operations for adding, updating and removing information of HRS
> + some code in RegionServer is puted in synchronised block... cause it is working with synchronised map...
> Note: this task is to make code much much more clear.. and it's not going to change logic, so no much problem is going appear
