[part10]Remove singleclient outdated api

[luqiang-guo]

删除multiclient 下single client的接口
总删除列表

此pr完成了一部分接口清理。

• FixedTensorDef
• MirroredTensorDef
• inter_job_reuse_mem_strategy
• acc
• hierarchical_parallel_cast
• pack
• parallel_cast
• unpack
• device_prior_placement
• fixed_placement
• InitEagerGlobalSession
• eager_execution_enabled

这个也没用了吧

[clackhan]

这种api_acc包一层的接口，都可以把对应的函数删除

[clackhan]

后面几个pr都是同样的问题，一起处理一下吧

[luqiang-guo]

好的我一起处理

[clackhan]

FixedTensorDef和下面的MirroredTensorDef可以直接删除

[clackhan]

同上

[luqiang-guo]

已经清理干净

[chengtbf]

没清理干净。。。这些都没删

[chengtbf]

这个也没删？
