Title: measure IMAP bandwidth based on mbsync/isync file transfers

The plugin "imap_bandwidth" runs the following steps in order to measure the bandwidth of one or more IMAP servers:
* generate a file with random content of configured size
* upload the file to the remote IMAP server via mbsync
* download the file from the remote IMAP server via mbsync
* upload and download bandwidth is calculated based on the file size and the duration of the upload/download operations
