    .SYNOPSIS
        Start a database export from an environment
         
    .DESCRIPTION
        Start a database export from an environment from a LCS project
         
    .PARAMETER BearerToken
        The token you want to use when working against the LCS api
         
    .PARAMETER ProjectId
        The project id for the Dynamics 365 for Finance & Operations project inside LCS
         
    .PARAMETER SourceEnvironmentId
        The unique id of the environment that you want to use as the source for the database export
         
        The Id can be located inside the LCS portal
         
    .PARAMETER BackupName
        Name of the backup file when it is being exported from the environment
         
        The file shouldn't contain any extension at all, just the desired file name
         
    .PARAMETER LcsApiUri
        URI / URL to the LCS API you want to use
         
        Depending on whether your LCS project is located in europe or not, there is 2 valid URI's / URL's
         
        Valid options:
        "https://lcsapi.lcs.dynamics.com"
        "https://lcsapi.eu.lcs.dynamics.com"
         
    .EXAMPLE
        PS C:\> Start-LcsDatabaseExport -ProjectId 123456789 -SourceEnvironmentId "958ae597-f089-4811-abbd-c1190917eaae" -BackupName "BackupViaApi" -BearerToken "JldjfafLJdfjlfsalfd..." -LcsApiUri "https://lcsapi.lcs.dynamics.com"
         
        This will start the database export from the Source environment.
        The LCS project is identified by the ProjectId 123456789, which can be obtained in the LCS portal.
        The source environment is identified by the SourceEnvironmentId "958ae597-f089-4811-abbd-c1190917eaae", which can be obtained in the LCS portal.
        The backup name is identified by the BackupName "BackupViaApi", which instructs the API to save the backup with that filename.
        The request will authenticate with the BearerToken "JldjfafLJdfjlfsalfd...".
        The http request will be going to the LcsApiUri "https://lcsapi.lcs.dynamics.com" (NON-EUROPE).
