Currently, it's used the archive.ReplaceFileTarWrapper
that requite a []byte of the files replaced. This is not
a good idea if files are big and instead could be better
in the near future reimplement ReplaceFileTarWrapper with
a callback that return io.Reader instead of []byte.
If a protected file is already present on target rootfs
it is created a file with the same prefix used in Gentoo:
._cfgXXXX_<filename>
* installer.LuetRepository is now installer.LuetSystemRepository,
a struct that extend config.LuetRepository
* config: system_repositories option is now "repositories".
This resolve viper issue.
* config: cache_repositories option is now "repetitors"
This resolve viper issue.
* cmd/*: Now use new config.LuetRepository
* cmd/search: now create local luet repository if database_engine
is equal to "boltdb"
* concurrency could be configured now from cmdline,
configuration file or LUET_GENERAL__CONCURRENCY env variable
* verbose option is now related to debug option
