    Validate parameters of agent API

    The agent API has some parameters, but they are not validated.
    Each parameter is stored to the table "agent_builds", and each column
    is defined as varchar(255).

    mysql> desc agent_builds;
    +--------------+--------------+------+-----+---------+----------------+
    | Field | Type | Null | Key | Default | Extra |
    +--------------+--------------+------+-----+---------+----------------+
    | created_at | datetime | YES | | NULL | |
    | updated_at | datetime | YES | | NULL | |
    | deleted_at | datetime | YES | | NULL | |
    | id | int(11) | NO | PRI | NULL | auto_increment |
    | hypervisor | varchar(255) | YES | MUL | NULL | |
    | os | varchar(255) | YES | | NULL | |
    | architecture | varchar(255) | YES | | NULL | |
    | version | varchar(255) | YES | | NULL | |
    | url | varchar(255) | YES | | NULL | |
    | md5hash | varchar(255) | YES | | NULL | |
    | deleted | int(11) | YES | | NULL | |
    +--------------+--------------+------+-----+---------+----------------+

    This patch adds the validation with the type and the length.
