Fix qa failures introduced by pmsearch redevelopment

[sfeifer]

Added the -S option to the newhelp man page.

Refactored areas of the code now that search functionality is not associated with the key server and instead uses a local sqlite database.

📝 Walkthrough

Summary by CodeRabbit

• New Features

  • Documented the -S/--search option for creating a SQLite FTS5 search index for pmsearch(1).
  • Search index creation now requires an output path and produces a directly named database file.

• Changes

  • Removed legacy search capability from web service and key-server setup.
  • Simplified initialization and connection processing while retaining standard help database and metric-series functionality.

Walkthrough

The change removes pmsearch server-side integration from slot flags, callbacks, configuration, and connection setup. The newhelp manual documents -S/--search for generating a SQLite FTS5 search index.

Changes

pmsearch server cleanup

Layer / File(s)	Summary
Search contracts and documentation src/libpcp_web/src/slots.h, src/libpcp_web/src/nosearch.c, src/libpcp_web/src/search.h, man/man1/newhelp.1	Removes SLOTS_SEARCH, reduces SLOTS_PHASES to four, deletes obsolete search declarations and wrappers, and documents the newhelp -S option.
pmproxy search integration removal src/pmproxy/src/keys.c	Removes pmsearch configuration, callbacks, setup reporting, search slot assignment, and search-only connection conditions.
Web connection cleanup src/libpcp_web/src/load.c	Stops enabling search slots for text sources.

Poem

A rabbit trims the search code
Four phases mark the lighter load
Newhelp builds its index file
Search callbacks leave the while
Slots now follow the simpler road

In `@man/man1/newhelp.1`:
- Around line 136-141: Update the newhelp output-file documentation to
explicitly state that the usual foo.dir/foo.pag files are created only in normal
mode; when the -S/--search option is used, -o names the SQLite FTS5 database
file directly for pmsearch.

In `@src/pmproxy/src/keys.c`:
- Around line 150-153: The discovery module setup in the keys initialization
path must handle archive-only configurations: when archive_push or
archive_discovery is enabled without series_queries, initialize a valid
discovery module or explicitly pass NULL rather than leaving
key_server_discover.module uninitialized; preserve the existing series_queries
setup and ensure pmLogGroupLabel/pmDiscoverStreamLabel receive the correct
value. Add matrix tests covering both archive flags with series_queries enabled
and disabled.
