Refactor Summaries

[ersonp]

Did you run make format && make check?
yes

Fixes #757

Changes:

• Changed Summary to Overview and ExtraSummary to Summary.
• Factored out TCPAddr and Online fields into its own struct NetworkStats.
• Removed extraSummaryWithDmsgResp and updated the new Summary accordingly.
• Renamed getVisorsExtraSummary to getAllVisorsSummary.
• Removed TCPAddr field from makeSummaryResp

How to test this PR:

1. Run make build-ui; make move-built-frontend ; make build; make install
2. Start Hypervisor and check ui.

dmsg stats is needed by both getVisorSummary and getAllVisorsSummary.

Seems to me like TCP address is not actually completely removed. If it is, then we can probably get rid of the whole network stats structure because

1. TCPAddr is gone
2. Online field is not actually filled by visor iirc so it does not need to be part of the summary.

"/visors", getVisors() and "/visors/{pk}", getVisor() uses NetworkStat but i do not know where the endpoints are used. I removed NetworkStat from them and everything still works but I will need more info on them. Online is used by getAllVisorsSummary() and the port in TCPAddr is used by getVisorSummary so I replaced TCPAddr with Port. Both getAllVisorsSummary() and getVisorSummary user Overview so Online and Port can't be taken out.

Working well, just 2 things:

• With the changes made, some parts of the UI code are no longer needed, but I checked and added them to a list, so I can make the changes after this PR is merged, to avoid delays with this one.
• I'm not a fan of updating the compiled UI files in PRs that were made for adding other changes, but if nobody else has problems with this, there is no problem.
