Introduce means to mark custom packages with (not necessarily security) advisories

• I.e. github.com/pkg/errors
• i.e. github.com/gorilla/*
• i.e. github.com/satori/go.uuid
• I.e. "this specific version of this library"
• I.e. "<= this version of this library"

With advisory_type:

• deprecated
• security
• other

select
  renovate.repo,
  package_name,
  renovate.version,
  renovate.current_version,
  advisories.package_pattern,
  advisory_type,
  description
from
  renovate 
  inner join advisories on renovate.package_name like replace(advisories.package_pattern, '*', '%')
where
(
   case
      when version_match_strategy IS NULL           then true
      when version_match_strategy = 'ANY'           then true
      when version_match_strategy = 'EQUAL'         then current_version = advisories.version
      when version_match_strategy = 'LESS_THAN'     then current_version < advisories.version
      when version_match_strategy = 'LESS_EQUAL'    then current_version <= advisories.version
      when version_match_strategy = 'GREATER_THAN'  then current_version > advisories.version
      when version_match_strategy = 'GREATER_EQUAL' then current_version >= advisories.version
      else false
    end)
