Incorrect variable argument type on configuration detach

[Petr Malik]

Change I65e8a8d5dc251a8b00529cdfb1a6ada3d5720f68 has switched from MySQL-python to PyMySQL.
This change surfaced an issue in the current implementation of configuration groups.

Detaching a configuration group may now lead to "Incorrect argument type to variable 'key_buffer_size'".

The restored default values read from the configuration template as strings
get quoted by Trove. MySQL however does not like numeric values quoted.

This issue is currently reproduced by MySQL configuration scenario tests.

    Preserve data type when parsing MySQL configs

    The data type information was lost in conversions.

    IniCodec should deserialize Python objects (like other codecs).
    guestagent_utils.to_bytes should return byte values as ints.

    * The IniCodec is also used by Cassandra.
      Tested with both MySQL and Cassandra scenario tests.
