According to the setting, the tenant code = linux user name. When the linux user name is underlined and other special characters, the tenant will be prompted [Please enter the English tenant code].

Temporary solution: directly modify the contents of the corresponding database table t_escheduler_tenant.

Expectations: Front-end validation logic can be optimized to allow for special characters.

按照设定，租户编码=linux用户名，当linux用户名带下划线等特殊字符时，创建租户会提示【请输入英文租户编码】。

临时解决方案：直接修改对应数据库表t_escheduler_tenant的内容。

期望：前端校验逻辑可以优化下，允许特殊字符的情况。
