Add DB Stats Command to Console

[h00die]

fix #13136

@leebaird 3yrs later :)

This PR adds a db_stats command which gives the user information about how much data is in their database/workspace. It is very similar to debug --database, in fact borrowing some code from there, however this prints in console friendly format instead of markdown. I've also added some quick calculations for services/host, and vulns/host.

Verification

• Start msfconsole
• have some hosts/vulns/services/notes/creds/kerberos_tickets in workspaces
• Verify db_stats prints out a friendly formatted table with the information

now with creds and kerberos ticket counts!

@cdelafuente-r7 right now the code loops through counts for each field when populating the workspace rows. Later it does a request for all counts, which in theory isn't needed as the numbers could be totaled up from before and stored. Save a few DB queries, thoughts? This is already partially done since just thought it may be good to expand it.

[cdelafuente-r7]

@h00die, yes absolutely, I think it is a good idea.

There seems to be a bug in the tickets_search function, when it calls tickets the workspace filter isn't being applied, it simply defaults to whatever workspace you are currently in. @dwelch-r7 can you check on that since you wrote that code?

Thanks for calling this out, this PR here #18400 should sort it

Thank you @dwelch-r7 and @h00die for working on this issue. The related PR is now landed.

@h00die, would you mind rebasing your branch? When it's done, I'll do a last batch of test and land it. Thanks!

rebased

Thanks @h00die ! Everything looks good to me. I'll go ahead and land it.
