[AMORO-3329] Add MemorySize for parsing memory value and unit

[Jzjsnow]

Why are the changes needed?

Currently, when we use flink optimizer groups, the memory parameters flink-conf.jobmanager.memory.process.size and flink-conf.taskmanager.memory.process.size only support plain numeric strings or strings with m/g suffix. If we configure them with mb/gb suffix, we'll get wrong parsed results. And the default unit for plain numeric strings is mb, which is inconsistent with the default unit of byte in the flink native parameter and may cause inconvenience for users familiar with flink when using this parameter.

Close #3329.

Brief change log

• Add a new class MemorySize to the amoro-common module for parsing flink's memory parameters, consistent with flink's native parsing logic.
• Update the values in the column properties of ams metadata tables resource_group and resource to automatically add the MB suffix to the flink jm and tm memory parameters that have been set and saved as plain numeric strings

How was this patch tested?

• Add some test cases that check the changes thoroughly including negative and positive cases if possible

• Add screenshots for manual tests if appropriate

• Run test locally before making a pull request

Thanks a lot for the contribution!

I think this is a good start to make our configuration value more readable.
We may improve our configuration format in other place, like the AMS configuration after this PR been merged.

I left a minor suggestion, you may want have a look!

LGTM.

Thanks for the contribution, LGTM

This patch is back-compatible, but it contains some user behavior change, maybe we need to add this in the release notes, @Jzjsnow could you please create an issue to track the release notes update, thanks.

Apart the above, do we need to add some documentation about how to configure this in the documentation? if this is yes could you please add an issue to track it. thanks.
