Basic vendor neutral follow-ups

[tisonkun]

There are still more than 3000+ references to "timecho" and even you have:

iotdb-docs/src/UserGuide/V1.3.x/Deployment-and-Maintenance/Database-Resources.md

Lines 70 to 80 in f49d04a

	<tr>
	<td>Within 10000000</td>
	<td>48core</td>
	<td>1</td>
	<td>2</td>
	<td>Please contact Timecho Business for consultation</td>
	</tr>
	<tr>
	<td>Over 10000000</td>
	<td colspan="4">Please contact Timecho Business for consultation</td>
	</tr>

This would NEVER be accepted. Please resolve the vendor neutral concerns in a timely manner.
